I'm ok with it being a part of the community we need to help the community grow, I am continuously looking for as paid signature campaign, but after the campaign I've joined, it sometimes took me a week or two to find another one so while looking I have something to wear that is worth promoting.
I think Idena hasn't had a plan to hold a paid signature, I see that there are still many people who volunteer to use the signature, maybe you can ask about a paid signature on their telegram, in order to get a response from them
