I have had not so much feedback despite addressing, as gently as possible, to them in their own language…
In my opinion one of the problems could be the way many new users decide to register to iNat. In this light I wonder how people become aware of iNat and then decide to register to do something on the site. Do they know that there are rules to be respected before registering? Do they read (and understand) the “getting started guide” aftre having registered?
For example, one of the Italian initiatives linked to the recent city nature challenges has been promoted on an institution website and on facebook without explaining that iNat is mainly devoted to wild species while encouraging participants to photographs as many organisms as possible to win. The result has been a certain (not too many to be managed) number of newbie all photographing and posting the same plants cultivated in a sort of botanical garden, of course without flagging the observations as cultivated. More or less no one reacted to the invitations to flag that kind of observations. I do not think this is because they were unpolite but just because they were unaware.
In the end, I think that we should apply a way to inform the new users on how to behave and to use properly the site but, at the same time, a certain work should be made in order to make the potential new users already aware of what iNat really is for.
