A good list thanks!

The problem with bots is that there is no quality control (on most of them anyway) so anyone can just post rubbish and boost it to 'hot' or 'trending'. It does seem that they are here to stay for now - I use them on my best posts - not shorter posts and competitions etc I see that as bad practise.

I think your right alot of people vvid right at the end and just muck up the profit for everyone else! There are plenty of bots so your best to just bid on the next one
