There's no need to get upset about what happened. It sounds like the moderator over there has just misinterpreted donations to equate to financial compensation that categorize our relationship as a partner, client, employer, or friend, per his statement:
> Sorry but my Blesta Signature dosent have to do anything with compensations.
Does it not clearly state that you've received monies from Blesta (and others)?
That creates a financially-influenced relationship between you and your donors, which puts them into the category of your "partners, clients, employers or friends.".
We don't belong to any of those categories, so the statement's conclusion is false.
I would also argue that the statement's premise is false as well, since contributions do not always imply financial influence between parties.
He seems to have acknowledged that that argument was falling apart, so he came up with another to reaffirm his stance:
> this warning is not breaking any rules
I beg to differ. Aside from the principle one that brought this discussion about, you included in your post:
"you will see many developpers like me sharing Plugins, Modules, Extension for free, helping blesta to grow."
Beside being self-promotional, another rule applies to that which I'll quote below for you for future reference:
"You may only discuss details about your company and/or product offerings when the thread starter or poster has made direct reference to your company and stated something untrue or misleading, or something which clearly needs clarifying. The response must be in direct reference to the point discussed only and contain no added promotional information and/or fluff. It is advisable when in the above scenario to contact us first."
The last statement is vague and open-ended, which gives them leeway to do whatever they want. I guess you'll have to sit in the penalty box for a little while.
