I've noticed on the hotlist lately that people have been putting their number of program votes in the thumbnail of their program. I've ironed out two in this screenshot. If you look closely, you can see that they both advertise their number of votes.
Don't get me wrong. I love to see the community growing, but this seems to be a form of vote soliciting. It's basically the same as saying "I have fifty subscribers!" on your subscription page. This has not been allowed nor disallowed via the guidelines, since last I checked. Many games on the top list such as Mini Putt, Lava: The Impossible Game, Doodle Dodge, and Funny... Ha Ha! all advertise this, but have not been taken down, so it appears that this is A-OK by the guidelines. Thanks for your consideration!
