Went up on Friday evening, was taken down yesterday evening.
AFAIK it didn't get much coverage when it went up (although there wasn't much time) but now there is lots of coverage.

From the bottom of my heart, I want to thank the trans activists to jump to it and complain about these posters. You are helping us achieve greater reach than we could ever have anticipated. And the people who pay for the posters get their money refunded. It's PERFECT.
Please carry on. PLEASE!
