What does spam look like?
Spam can look like many different things. It could be emails that have no meaning to your life, texts that are sent over and over to you for no apparent reason, and it may also look like the cost of your bills going up.
How to avoid spam:
If you want to avoid spam, its probably a good idea to get a spam filter. This will help a lot! Another way is to just ignore the message/email. There is a high chance that the person spamming you will just get tired of it. A simple way is to have an email account that you would only use to sign-up for stuff.
