I never really looked at reddit.com, I had a quick browse and can't be bothered going through it.
I have seen a post in steemit saying that his/her ad on reddit got rejected. Well of course they don't want competition. Apparently reddit.com tried a tipping bot before with doge coin but did not work cause someone stole the money... and now they are trying to bring it back again... interesting story if anyone can be bothered doing the research.
