Two things, screenshop OP:

Firstly: when you post your work to a public archive, you do not get to chose who interacts with it except within the bounds of the controls that the archive you upload to extends to you, via blocking, limiting access to logged in users, etc.

Secondly: Proshippers do not make those kind of “threats as jokes” that is the difference between proshippers and antis.

btw I am screenshotting this instead of interacting with it directly merely because I feel like extending the courtesy; I would be completely in my right to respond to it via reblog.
