Is it possible to make threads where other members can recommend several threads that are eligible to be locked/deleted by including a number of reasons that can be considered by the Moderator? besides reporting it.
The logic is the same as the thread made by LoyceV:Mod, please check new plagiarism: Reporting copy/pasting, please permban
Sure. You or anyone else is free to create such a thread if you wanted. Nothing stopping you. No guarantees that it will be enforced though but people can chip in whether they think a thread has outlived its purpose.
I think the best solution would be to set a default time of expiry for every thread created. OP would still have the option to re-open the thread if needed, otherwise it should remain closed.
If we were to talk about expiry times, I think 1 week would be good enough.
One week is too short. Setting some sort of automatic expiry would just lead to too many issues and closing threads that people still find useful. Users would likely then just open a v.2 version of it anyway. A much better fix is to tackle the issue at the source of the problem which is crap campaigns that are paying people to make the spam in the first place. Punish that and spam will stop or at the very least lower.
