He followed her on twitter after banning her on tumblr and receiving massive backlash due to his reasons for banning her.

PhotoMatt specifically spoke about the banning of Tumblr user Predstrogen, saying that she was removed from the site for posting a threat against him. The post in question read, “I hope photomatt dies forever a painful death involving a car covered in hammers that explodes more than a few times and hammers go flying everywhere.”

In an email correspondence with Know Your Meme on February 21st, 2024, Mullenweg stated that the account was not suspended for a single threat. When he reached out, Mullenweg listed the reasons for Predstrogen’s suspension as follows:

Mis-tagging adult content against Tumblr's community guidelines, repeatedly.
Harassment of numerous other Tumblr users, not just me.
Multiple threats of violence, not just the one I shared.

Mullenweg also acknowledged that his sharing one example of Predstrogen’s “multiple threats of violence” may have confused readers and that he considers the phrase “I hope photomatt dies forever a painful death” a “very scary thing to read.”
