Voting Question: How do I stop people from using my address?

I appreciate everyone who has answered my previous question but I was not as clear as i could have been. My email has not been hacked, someone is just using my address to join websites. Some websites don’t require a verification email, so whoever is using my address is trying to join sites like that. I do get a lot of spam, but i do have a feeling that this is an actual person that just doesn’t feel like making an email for themselves. I also do not want to change my address because I’ve grown attatched to the one I have! Again answers are greatly appreciated!
