Hi,

Maybe not a full ban (or maybe, I wouldn't be against it) but at least some clear rules to avoid these spam.

My 2 cents:

An example of mail that should absolutely be avoided (and not just on this mailing list) is when a similar mail is sent several times in a short timespan. We had almost the same mail sent in 2 days this week ! (not to blame this person in particular, this is not the first time it happens and it's bad communication).

Also, senders should strive to make an effort to tell us how the call is related and/or could benefit to/from Wikidata (very often it's unclear, we shouldn't have to guess why we are receiving these calls).

Cheers, ~nicolas
