The person has spoken to OP regarding callout.

I'm not happy about links being removed but weasyl does have a TOS that needs to be followed, assuming I am asked to remove my link as well.

The tumblr post is still out though and they [tumblr] have yet to silence us.

By no means should this issue be ignored. We do indeed have a member of weasyl staff with a history in underage pornographic art, and this is still highly problematic for weasyl and its community. I do not stand for this kind of activity to go unnoticed, and I am still angry.
