Toonblr 

A community full of furries and robot fuckers. These Tumblr dorks completely deface the purpose of a children's game.

"I'm looking through the Toonblr tag and I found this porn of a furry and a robot. What the hell."

Tronblr 

A group of roleplayers on Tumblr, with a surprisingly large fanbase, that extends into other fandoms.

Though Tronblr is known most for their slash and unapologetically self-aware crack they are also known for having rich and entertaining characterizations of those that they play.

Also there's crossdressing.

Tronblr just about exploded the other night. The Joker showed up.
