Who are the internet troublemakers?

I’m trying to make a list. It may or may not be for a writing project I’m working on. OK nevermind, it is. I’m trying to compile a list of 100 hackers, pranksters, culture jammers and revolutionaries that changed the web. I have a good list already but I’m wondering who you think should be on this list as well? Important note: As this is a list of “internet” people who “changed the web” anyone suggested should have done something noteworthy online. There are a lot of amazing pranksters and culture jammers out there who aren’t doing things online so they wouldn’t be on this list. Also, I’d prefer people over groups, though I know that in some cases a group is the only option. Suggestions??
