So I've noticed that most if not all of these spam "advertiser" scumbags seem to have some things in common and maybe these will help otherr find them out:

PC Specs in Bio
Counter Strike 2
Team Fortress 2
Community Leader badge on display
Always adds you out of the blue

If you find any other details that they have in common feel free to mention

Usual run of the mill advertising for a rust website offering item drops...Also TIL that even when I aks them directly before they send anything they just paste the copied message right on over without batting an eyelid :/

Most likely compromised accounts turned into bots that now add people and get you to sign in to a website called "RustPush" that REQUIRES you to sign in through steam..... (https://imgur.com/a/wPLw11o)

Advertising for a "Rust Roulette" site and wants you to put the website's name in your bio...
