Excellent article! I don't use bidbots, at all. I tried once or twice, but I didn't see the point in using them to vote my posts.
The only reason I see to use bidbots is when my VP is too low, and I want to reward somebody else's post. In that case, I can make a bid to his/her posts... and still maintain my Voting Power.
Thank you, @trincowski. It would be ok, if you get more then you pay, but loosing money this way sounds crazy to me. Thanks for your support!
If it were profitable, everyone would abuse the system. The Trending Tab is already horrible because of the bidbots. With profitable bots, it would be even worse.
