It does not give a good impression if your first and only message to an
email list is a cross-posted advertisement that does not make any effort
to clarify the relationship to the topic of the list. We don't usually
have such calls here (as opposed to other lists, where you have many
messages of this type every day). If you have a relevant message for the
Wikidata community, please take your time to write a personalised email
that clarifies why people should be interested.
