I'm not sure if it's just the larger instances getting the brunt of it, or if we've been quietly handling it in the background, but I just wanted to float the question in case it's something you have to be actively looking out for.
I would hate for this community to get taken down due to bad actors elsewhere.
Midwestsocial is federated with world where the spam is happening so yea its vulnerable, your admin could disable images or temporary defed but none are true solutions. Hopefully the next update brings new mod tools to deal with the spam in the future
