Kacer

I meant v4.
 
You could install it directly from Git if you wanted, but I haven't yet written docs for new chat support. The new code is here. To call getGroups for example, you'd do user.chat.getGroups(...)

I noticed that limited accounts are able to join and post message on group chat/channels. Hence, I fully support you that this is indeed a method that could be abused. I'm astounded that steam restricted all community features, but yet, they left the most essential feature wide open to spammers and spreaders.
