I have not changed the DC Discord logo or done anything else activism-related in the VHL in quite some time, but I always tell my players that if it would mean something to them if I rainbow-ized our logo for a month, then I would do it in a heartbeat. It being meaningful for someone in the community - be it someone LGBTQ+, Ukrainian, or any other group that has been under attack - that's why we change our logos.
Just my two cents anyways. Basically not doing it proactively but if someone assures me it means something to them on a personal level, I'm all for it.
