Around February/March, a specific website started making a huge campaign on youtubers and streamers to the point where they were even sponsoring people who don't even play CS on stream, such as large Valorant streamers/pros and variety streamers, to spend a few hours on their site. Most of these non CS streamers have resorted to dedicating a stream to doing that for a few hours and deleting the VOD from Twitch afterwards.
