Problem: Article: Most of the time, spam comes from an unrecognized sender, often with odd email addresses. That doesn’t mean all unrecognized email is spam—legitimate newsletters, website administration emails (password resets, authentication requests, etc.), and more may come from addresses you don’t recognize—but spam emails usually have multiple numbers, dashes, and/or odd letter combinations in them. The goal of most spam emails is to get you to click on a link, so only click links in emails from people who you know and trust. If you're unsure of a link in an email from a friend, consider calling them and asking about the link. The case may be that their contacts list was compromised by spam. Spam often contains misspellings and oddly-worded sentences. This can include bizarre capitalization and weird punctuation, or awkward formatting such as bolding, italics, and randomly colored text. Anything that claims you won a contest you never entered, offers you access to unclaimed money, or promises free electronics, jewelry, or anything 100% free is never legitimate. Any message that asks for your password is never real, as all legitimate websites have automated password reset programs. Requests from strangers should always be ignored. Many email services have a preview window which will allow you to read the beginning of an email message without opening it. “Robots” (scripts created to scrape websites for addresses) can quickly gather thousands of emails at a time from websites where the email addresses are made public. Avoid entering your email address to sign up for things like coupons, and never type out your email address in a comment or post online. If you must provide your email address in a public context, try writing it out in creative ways (e.g., "name [at] yahoo [dot] com" instead of "name@yahoo.com"). This will prevent would-be spammers from pulling your email address with an automated program. Usernames are almost always public, making email discover a simple matter of figuring out the correct service to add at the end. Services such as Yahoo! Chat make this even easier, since chances are everyone using it has a @yahoo.com email address. Replying or clicking the “Unsubscribe” link will only generate more spam, because doing so confirms that your email address is valid and active. It is best to report and delete the spam using the steps in the following sections.
Summary: Check who emails are from. Avoid clicking on links in emails. Check the email's spelling. Read the message. Don’t give out your email address online. Make your email address unscannable. Don’t make your username the same as your email address. Never respond to spam.

INPUT ARTICLE: Article: You won’t be able to identify the size of the leak or effectively repair it until you remove all of the road grime, dirt and rust from the pipe around the hole.  Use a steel toothed brush to scrub away the grime, being careful not to get any in your eyes.  Scrub the pipe all around the leak, including the top side if you can reach it. Make sure to wear eye protection when scrubbing the piping to prevent anything from getting in your eyes. Sandpaper will remove any last bits of dirt and debris stuck to the pipe while scoring the steel surface to better stick when you apply the patch.  Rub 80 or 100 grit sandpaper back and forth along the exhaust pipe around the leak you intend to seal.  If you are using exhaust tape, make sure to scrub the top of the pipe as well. Roughing up the surface of the metal will create a stronger bond for the patch. Acetone will ensure the metal is clean and free of anything that could interfere with the seal created by the exhaust tape or epoxy.  Acetone is the primary ingredient in nail polish remover, so you may use nail polish remover for this step if you’d rather not purchase acetone strictly for this project.  Be careful not to drip acetone in your eyes or mouth while cleaning the pipe with it. You can purchase acetone in the cleaning chemicals section of many retail stores. If you are using exhaust repair tape, wrap it all the way around the part of the pipe with the leak.  Continue to wrap the tape around the pipe for a few inches to either side of the leak to ensure there is a good seal.  Different kinds of exhaust repair tape will require different application methods, so be sure to read the instructions before you get started.  Some exhaust repair tape needs to be applied to warm pipes, so you may need to start the vehicle and let it run for a few minutes before applying. You can purchase exhaust repair tape at most auto parts stores. If you are using an epoxy to seal the leak, mix the two chemicals together using a wooden dowel.  It will begin to cure immediately, so apply it directly to the leak as soon as the components are thoroughly mixed.  Dab the epoxy onto the leak, then use the wooden dowel to spread it around the area.  Make sure to cake the epoxy over the leak and surrounding pipe so it creates a thick film on the whole area.  You may also choose to wrap the leak in exhaust repair tape after applying the epoxy. Different types of epoxy have different curing rates, so read the instructions on the package to know how long let the epoxy dry.

SUMMARY: Scrub around the hole with a steel toothed brush. Prepare the surface of the pipe with sandpaper. Wipe acetone on the pipe around the leak. Wrap exhaust tape around the leaking portion of the pipe. Apply epoxy to the leak.

In one sentence, describe what the following article is about: On the bottom or outsole of the shoe, run a wipe between the rubber grooves.  Take a fresh wipe and gently rub along the edges of the boost.  After you use the wet wipe, gently dry the boost by wiping the edges down with a paper towel. Any wet wipe will do, although you may want to use one with antibacterial or stain removing properties to help remove dirt. If the marks don’t respond to a wet wipe, a bleach pen may be able to lighten the stain. Take the cap off and rub the marker over the stain completely. For the best results, put the shoes in the washing machine afterwards. You can get paint pens and oil-based markers at craft stores. Take off the cap and gently run the tip over the stained area. You may need to go over the whole boost so that the entire sole is the same color. Let it dry for a few hours. Paint pens and oil-based markers can give off fumes. Make sure you are working in a well-ventilated area. If you start to feel dizzy, take a break.
Summary:
Run a wet wipe along the bottom and edges. Use a bleach pen on dark or stubborn stains. Hide permanent stains with a white paint pen or oil-based marker.
