I was looking for one of my threads and found that was locked. It seems like I myself have locked the thread, actually I can't remember. However, there's no way anyone can know who locked the thread without the author. Is it possible to know, missing anything?
Wouldn’t it be good if we had the stats who locked the thread? I can't see it anywhere for now.
I have lucked a thread myself once. Haven't tried unlocking because, it was irrelevant to do so. I take a scenario with ignoring users to offer similar idea to lucked threads. Lately, I've ignored quite a few users unknowingly and each time I do come to realise what have been done subconsciously, I unignore and its all good.
I think the same goes for locked threads too. As, you can't unlock what you never lucked yourself! When you memory doesn't help you to recall, you just attempt unlocking to see if it's doable and if not, your sure to know its the work of one of the mods. Hope that's it though because, troubling mods over a post could result in some drastic actions. Saw one once with a moving and return of threads between boards with a user and a mod.
