I think it would be better to make a bot that replies to shitposts with a warning letting the poster know they are shitposting. Something like:
Warning: your post appears to have been written by an NPC. This question has been asked on the forum approximately
43 times already, with the most recent merited reply being the following:
We can prove that the number of provably lost bitcoin is 2,828.654 BTC, and this number can be safely removed from both the total and the circulating supplies. Anything which is not provably lost should not be considered removed from the supply.
Consider performing a simple Google or forum search before posting a question on the forum next time. Thank you for your cooperation.
But how will the bot know if that question has been asked 1000x?
There are many ways to ask the same question without repeating yourself, so it's nearly impossible for the system itself to know it's the exact same question.
And what guarantee is there that a question that has already been asked 100x cannot generate a very interesting and instructive debate?
There is a way to answer some questions, from different perspectives that might be interesting and helpful.
I agree with @bullrun2020bro.
I don't think the OP idea is unreasonable, but I think it would be too complicated to put all the possible variables so as not to penalize anyone.
