About the Polls (Patreon)

I was talking with a patron the other day about the polls and they where concerned that the polls aren't fair enough. See the issue is that ideas that seem to involve my OCs have been getting picked on the regular. 

Now I don't add my ideas or my OCs to the poll, unless a patron asks of them or if there is only one person in the poll idea tier. I have been aware of this issue in the past, in fact its the reason I added the commission tiers, so maybe I should consider making more changes to make things more fair.

Really the only thing I can think of is to ban my own OCs, or copyrighted characters from the polls. What do you all think, what could I do to make the poll more fair to people?

Or maybe I could do something bigger, like removing the poll idea tier adding a few more commission slots, and having to come up with my own ideas for polls,

what do you all think?
