Valve fixed a vulnerability that allowed spamming group invites in Dota menu

Using a vulnerability in the Dota 2 client, hackers launched a script that constantly sent invitations to a team or guild - due to the frequency of requests, it was impossible to block them. At the same time, after accepting the invite, the attacker instantly left the group and continued to spam. With the new patch, the client will automatically decline team invites when searching for a match.
