Tbh I hated the steam events too especially when they mess with other games but they do get the servers populated. Steam should have thought this event thing out more thoroughly, if someone join 50 steam groups and each one puts up an event a day then that's a lot of useless spam.
The names of the events are just to catch peoples attention but if we say "Hey join x server," depending on the time of day you can get 5-20 people in that weren't playing. Sometimes the events do get spammed because there's several of us with mod in the group who know they work so we'll put them up and then someone else does or in my case I'm drunk off my ass and I want to play with people.
