Spam Emails

Register on weird websites and services and they'll come whenever the website sells your data to someone who will send you ads and stuff.

Why would you want to do this? You want to mess with them or what? lol
Like Cloud said just register on suspicious looking sites and you'll get them.

i just wana mess with them but dont know any weird websites

Just sign up on surveys by Janne Erikson duh simple

Put it into everywhere that you can. Put it online in random forums so that it can be picked up by scrapers.
You can also use those spam thing apps, like mentioned above. Just sharing it in public places is probably your best bet though.

Especially on Tech Support subreddits, or websites.

Don't register your email nowhere on the internet, it might be leaked by some database failures

You could start posting in newsgroup using a real email and the magic will happen
