From the Dota 2 website:
Today, we permanently banned 90,000 smurf accounts that have been active over the last few months. Smurf accounts are alternate accounts used by players to avoid playing at the correct MMR, to abandon games, to cheat, to grief, or to otherwise be toxic without consequence.
Additionally, we have traced every single one of these smurf accounts back to its main account. Going forward, a main account found associated with a smurf account could result in a wide range of punishments, from temporary adjustments to behavior scores to permanent account bans.
The ranking system is complete dogshit in League, and people instantly dismiss you when you say elo hell is real, because if it was, all these coaching sites like SkillCapped, GameLeap, ProGuides, etc wouldnโt be able to sell you their own brands of snake oil.
Riotโs customer support is also dogshit. The amount of in-game reports, Zendesk tickets, and posts on Twitter/X that have been straight-up ignored are through the roof.
