@puniko I got one such mention myself from an empty account supposedly asking for mutual aid, and AFAIK some other people on udongein got similar messages for other stuff some time ago...
@puniko But it seems to benefit the overall scam side of it, I mean, I don't think a lot of fedi people would fall for such a suspicious behavior that isn't a norm here, but still, now you actually need to look at it to understand that it's suspicious instead of being thrown into your face so much you already know it's a spam wave...
