Just don't be deceptive. If you are running and only have 1 or 2 slots say so. I've only had one bad experience. I joined one that was advertised as last in opens and joined a clan group of 3 where they obviously only had one slot. I politely warned them it was against community etiquette and they played dumb before one of them said he used the wrong macro. I still opened and left, only to see them called out in chat for the same thing 15 minutes later.
I do join t3+ that require an open fairly often. I value the blood shards more than the stash of rift fragments I have at this point.
