Clearly you aren't going to have much of a negative effect on the rewards pool, or gain much more visibility with those bids, and on this scale there is an arguement that a boost into 'Hot' for your chosen tags is reasonable.

The problem arises when everyone is at it, 24 hours a day, across 100+ Bots, which has been the case since late last year. Large stakes have moved away from curation to these bots, and this is continuing to be the case.

If you are into video tutorials, have a go with utopian-io and look at anything open source. Dtube prefer people over screen capture imo.

Good luck!
