I don't know what threads they were or what I said in them
There are two cases that may apply here: a topic can be so derailed and taken off track that it end up being deleted. Unfortunately when that happens then other people's comments go with it. I'm hoping to make it easier to prune things more selectively in future so that will happen less.
The other situation can happen when things are just 'spammy'. I've been going through the archives and unfortunately some people decided to trash topics by posting endless pictures of monkeys or plain gibberish and again the topics are then of little use to anyone so when they are removed your post count can go down.
Other times the topics are transitory and refer to an issue that is dealth with and simply makes no sense to leave up.
So basically we just have to trust an unknown group of people to have our best interests at heart? It's hard to trust people we don't know, who take actions that are not documented publicly. One cannot even see if someone is banned or for what reasons they were banned. I hope that you at least have a backend way of seeing what your mods are doing.
No, if something is removed then assume that I did it.
Whether or not I chose to post the reason why or not is my choice. If I think it's a mistake on someone's part or the rules need to be made clearer, they are changing or a reminder given then I will. Often times it would be unfair to focus on one person when it's several people involved so the notification may not be as pointed as you seem to require.
I think the reasons that people are banned are usually obvious. If you don't know what was going on then unlucky, this isn't meant to be a soap opera. If someone has demanded their account was deleted and is telling you they were banned then unlucky - you are being played. If you think I'm just being a mean bastard then unlucky - I don't really care .
Sorry, but that's the reality. If you don't like how the forum is run then go elsewhere.
