Also raiding websites doesn't work anymore because websites aren't one large community like they used to be. Tumblr is a blogging website with tons and tons of different subcommunities and content within. You can raid specific SJW blogs but that's about it, it won't affect the site as a whole.
It's also the reason why leddit raids aren't possible and raids as a whole don't happen/aren't funny anymore.
The last funny raids were the gamespot character poll and Club Penguin raids. It's gone straight downhill from there.
