What sites/apps do you sell?

Hey everyone,
I've been modelling for a little bit now and I've been hearing about some people selling access to various sites or apps the model uses, like access to a protected Twitter, their Snapchat name, kik, etc.

What do you use? What apps and sites seem to be the most popular and model friendly?

Password Protected Tumblr is the only one I use, I change the password once a month, memberships start at the first of the month. I already have 3 twitters but I think about the protected twitter subscriptions occasionally, it sounds like a decent idea if you can keep up with it.
