that's retarded, like those dumb sluts on reddit who get upset when someone shares their nudes on another website, or they get recognized. NO DUH. you put it on the internet, you should expect and assume that people will share it everywhere. if you can't handle that, then don't post it.

you can also just lead a double internet life and have two separate usernames and try to make your styles different enough that people don't notice it's the same person or at best can only suspect without knowing for certain.
