There are too many forum boards, which in fact not needed. Like Bitcoin Dissussion - all child boards - Press, Meetups, Important Announcements. In Important Announcements - all threads are outdated. Or in Meta - New forum software and Bitcoin Wiki - threads are also outdated. And much more forum boards need deleted.
Good example - In Important Announcements first page newest thread is from 2018, majority from 2013.
Much less forum boards can give a lot more info for members, which is not so complicated and not outdated.Hope forum admin give me higher rank for good suggestion.
So far board removing action is not yet taken so far. deleting full board will result in lose of so much data and there is chance that we would loss useful data also. There is option available for
report to moderator , If you think that any thread should not be on this forum more than samply report it. If admin agree and feel like you, he will delete it .
instead of deleting boards is best you say dead or old post that are not relevant to be deleted insteed
It is not easy to delete all old post. many thread in service, bounties section are totally inactive and no chance of activity in the future but still these Thread are useful to check the scammers/alts and other useful information. similarly many threads, inactive for long time contains idea of members which is I think somehow helpful and shouldn't be deleted.
