what would you propose instead ?I don't want to look like I'm in prison if a thread of mine gets locked (for whatever reason). Imagine a new person to forums coming in and seeing a lock (negative connotation, generally) on top of their avatar - what would their impression be?
I believe they said the current icons being used are going to be replaced later on, but I'm not sure if that means the size will change. I personally think they're fine.I went on a manhunt looking for this supposed lock icon. Trying to find that tiny 16x16px icon was not very intuitive, especially since it's floated to the right. I know that most forums would use a custom skin anyway, but at least make the icon larger if you're bent on not moving it somewhere more eye-placement-worthy.
If you don't want them to read it, then move it to trash/rubbish/insert-your-garbage-thread-collecting-subforum-name-here. I'm not saying your opinion isn't valid regarding XF leaving it the way it is, but of course people are going to want to read a locked thread that's in plain view, it's human nature.A lock on a thread is like tossing fresh meat to a group of sharks, people will quite quickly figure out which threads are locked then scurry over to read them so they can read why it was locked. I really like it the way it is.
