...I just found out that tagging @ everyone on Mastodon ACTUALLY DOES FUCKING TAG EVERYONE??????

@charlotte What do you mean? Sunbeam City runs on vanilla Mastodon but I still got pinged somehow

@hazelnot the publisher instance decides the pings in ActivityPub

@charlotte Lmao what the fuck ActivityPub is a trainwreck

@hazelnot it makes sense because you have a
publish post -> scan for mentions -> ping the appropriate servers

instead of

every server scans every post for the off-chance that it contains a ping

@charlotte Yeah but the receiving server could, like, reject shit like this even if it does receive it.

@charlotte Just seems like a security hole to me lol, but it probably will never be fixed because Gargron is in charge

@hazelnot yeah there is a real lack of validation for masto
