And the vast majority of people who use locking legitimately do so in order to prevent 3rd parties from derailing or distracting from the point of the OP. Forcing this cool down window will completely disable ones ability to have a locked thread and result in even more conflict as people play games to abuse that window. Nothing is stopping people from making their own threads to criticize any wrongdoing.
Well, as I said, I'm not sure if the pros would outweigh the cons and I doubt theymos would implement it anyway, but I think your situation would be in the minority here. In those cases I would suggest just self-modding, but as suchmoon mentioned, in this alleged instance it obviously wouldn't work in Meta. I think self-modding is important, but I also think it's important we don't have it in Meta, but I guess you've found a work around that (and not that I blame you for it), but I still think in the vast majority of cases the locking is abused by the nefarious, but again, not sure whether it would be worth changing.
Bad idea with a cooldown time , because of this 1 case here , theymos doing the same with hist Trust DTLog thread and its meant that nobody should post in it !
I highly doubt that. I'm pretty sure theymos can just post without unlocking the thread.
Admins/Globals can post in locked threads. In fact, maybe any mod can in a thread in their jurisdiction but I'm not sure.
I'm guilty of unlocking and locking one specific thread when I need to update it. The thread is in the archival board, so I wasn't able to make it self-moderated, and I don't expect anyone to post in it anyway. Nonetheless, restricting the ability to do so would be a drag.
Otherwise, I think you're right. Most of the time it's used by scammers to bump their threads in the currency exchange, digital goods, and account and invites boards. I can't see Theymos implementing the suggested restrictions, but if I'm wrong I wouldn't mind if those boards are the only ones affected.
But how often do you update it? I wouldn't be for it forever being locked but just possibly restricted to curb abuse.
