I've been to forums where you were allowed to lock your own threads.
Can't remember too much but the privilege was usually removed after a while.
But it's all about thinking before you post especially if you know a certain topic tends to get more unfavorable posts.
I can think of about 4 people who would do this often
2 no longer come here, one hasn't done it for a while and the other does it on a bi-weekly basis
I just want to bring this up again because it happened AGAIN.
once you post it to the public it should be considered the public's, not yours.
I just went and skimmed that thread and I think a lock, while not necessary, was well reasoned ._.
A thread in BR = off topic is allowed. That doesn't mean completely derailing someone's thread is allowed. I think this is very important to understand. Just because off topic is allowed doesn't mean that derailing threads with personal conversations and inside jokes should be accepted as commonplace. I think there have been discussions about this before, but the random spam posts that aren't fun to read for anyone except the few involved parties make Nation seem all the more cliquey and unfriendly. Filling up a thread someone made with "kitae pls" or whatever could very well make the OP want to lock it, and I see the reasoning behind that.
If you want an off topic thread, then make one yourself. Don't shove all your irrelevant posts that have nothing to do with the OP into another one.
Don't get me wrong, I've seen a lot of misuse for the locking rights, and I fully agree with limits being placed on them, but I don't think this was in abuse of them.
I haven't read the thread you linked, but from what you've said, I'll tell you that random spam about parodies and inside jokes is quite different from a proper discussion. If a discussion was still going on, and a real discussion, not random shit, then there's no reason for it to be locked. When the OP feels like you're just filling up their thread with meaningless posts that no longer have a relation to the topic at hand (note, thread about abortion, debate about abortion =/= thread about losing friends and weed, spam about parodies of a song), then why can't they request a lock? If they felt annoyed by people basically killing their thread, and there wasn't any real use of the thread anymore, then a lock is just fine.
Basically, you're saying it shouldn't be locked because you guys were using it, or whatever. Yeah, but "using" is a vague term. It's not like you were having any sort of meaningful discussion. It wasn't an intellectual debate, it wasn't talking about the OP, half of it didn't require a brain to post. It was just spam. You can easily do that somewhere else, without losing much of the conversation in the first place.
I don't even care about the locking right now, what I see from that thread was just rudeness. To refrain from spamming up someone's thread when they clearly don't want you to is just manners. Yes, it may be allowed, but it's in poor taste, and I don't see why you have to whine about the lock (on that particular thread), when the discussion (if you can even call it that) was going completely off track and had no content whatsoever.
Like I said, it's just plain rude.
