Stuff like that comes across as SO negative to me! If you're at the point of being so frustrated you want to make your topic something like that, I think it's time to log off for the night.
You're much better off, in my opinion, having a variety of things to offer in your topic. Like a main countdown, then smaller things they can tip for that will also count towards the countdown (flashes, spanks, liquor shots [within reason, be safe!], etc), a video deal, a raffle (if you're into that sort of thing, read
this thread if you get verified), Snapchat, fan signs, exclusive photos, etc.
I think all models can empathize with the feeling of "how do I make them understand that I need tokens for this" but I think maintaining a positive demeanor & offering a variety of options for guys to choose from is much better than coming across as negative.
