No, that's not it. It gives an impression that they care - leaving it open. As if they actually encourage discussion about the ruling, instead of being tyrants doing whatever they choose. The fact that no one has responded to any of the invited complaints tells otherwise, but it still looks more 'open-handed' to leave the thread unlocked. This way people will continue to think their opinions matter, even when they don't. If they just changed things, locking threads behind them, it wouldn't be a very good (too visible) display of control. Since there are supporters dissing the few who bother to complain, the sticky serves its purpose. It's living proof that they're only doing what the members want them to, and anyone with complaints is more than welcome to express themselves. Just as long as they don't expect a response.
Another impression it gives is that some future member might post a topic idea here to find out if it's 'pointless' or not. Hopefully it will spare them from having to make more threads when they start banning other topics from the discussion forum. This sticky can stand to represent all pointless things the site is better off without, open so the agreeing public can add their support (think of the 'newbies: how to make an Avatar Music Video' thread - half flames) and so the confused members can ask questions (and perhaps avoid potentially pointless thread topics that no one has thought to ban outright yet)?
So long as the spam is kept down, and people praise the decision, there's no reason to lock it. And in that spirit, why not suggest other topics to eliminate to help the admin out?
'Favorite Avatar' polls
any polls
boring Avatar posts (dbz, yyh, eva, bebop, anything your average newb might want to talk about that we've already seen a thousand times - we could just ban any Avatar on the 'most used' lists to keep the pointless repeats down)
'what if' threads - (haven't seen any lately, but they were big for a while there)
'recommend me' threads - (if they want to know what Avatar people think others should watch, they can just look through 'favorite Avatar' lists - no different from the 'favorite Avatar' polls)
I'm sure people can think of lots more. They've already started locking these 'pointless' threads, so why not have them listed here so the people posting them are warned ahead of time not to bother? After all, you can hardly fault people for breaking rules that were never stated. Drop them here and you can get it in writing.
