adjusting the downloads limit for crate deletions

[edwloef]

For about half a year I've been waiting to delete an old crate of mine, that I know for a fact I have only ever used and is currently unused, in order to free up the name. However it seems the bot traffic on it is close to or over the 500/month limit, presumably because it has 12 published versions (all yanked for that half year). All published versions seem to all be downloaded together by bot traffic, since their download histories are nearly identical.

I apologize if something like this has come up before, but I can't find the discussion that led to the concrete current 500/month limit. I would like to suggest reformulating it to something that takes bot traffic on crates with multiple versions into account. This could possibly look something like this:

• the crate has been downloaded less than 200 times for each version and for each month it has been published
• the most-downloaded version of the crate has been downloaded less than 500 times for each month it has been published
  • something this needs to exist to prevent spamming new versions to get under the first limit
