I’ve seen this commonly as well—this seems to be much of the basis for the sentiments expressed in this thread, for what it’s worth.
Requesting them be moved to new threads seems reasonable to me. Additionally reducing the inactivity threshold for warning to 2 months (or maybe even ≈32 days) as well as perhaps considering an e.g. 6 month (or perhaps less) auto-close for threads in the Python Help section specifically, would help reduce this happening in the first place without requiring more manual moderator burden (which other moderators have previously expressed concerns about).
What do you think, @davidism ? And what about other community members (particularly those, like yourself, active in helping out in Python Help where this problem is concentrated)?
