Out of the last 15 topics locked in the lounge, Gram has locked only 6 of them. I don't think that is a particularly high number, considering he is the most active Lounge moderator.
While he could do with warnings and questions before locking threads (like in your thread posting first to ask why you're not just using the other list), most of his locks were not bad decisions if you ignore the fact that they were rushed.
I have spoken to him and we agree that his locks would all appear much more justified if he would start posting first to ask questions and warn people that the thread is about to get locked for <whatever>, rather than just locking it right away
