For the most part I try to make what other folks are doing not my business. Twitter was enabling some pretty horrifying shit for a long time, but putting a "take this child actress's dress off" button on there is a level of "what the fuck are you doing on this site" that is hard to grapple with.
if you still use Twitter please understand that you are enabling and supporting this. It’s only going to get worse, so you may as well leave now and start rebuilding your “following” anywhere else.
