Hi, I'm the developer of @trufflepig (and a great fan of @ginabot, otherwise I'd never saw your mentioning :-)).

Quite a coincidence, I had kind of a discussion about bid bots today. Full disclosure, despite having them used myself, I'm not very fond of them. To my mind plain bid bots are more harm than useful to Steem. If you can simply buy upvotes, this platform's premise, the proof of brain, is eroded.

However, I also don't think bid bots should be banned or frowned upon either. The last thing that has ever worked is a prohibition. Besides, if people want to sell their vote, let them. However, there should be means or ways to encourage people to invest money in a way to help this platform in general, so that everyone benefits. If this means adding some kind of quality control to bid bots, so be it. However, the simple stuff that most bid bot owners label as quality control (not older than 3 days and at least 2 paragraphs) is a joke. The stuff that @trufflepig does might hint a bit more in the right direction, but is far from perfect.

Well, and to be honest, I did think about creating a bid bot with parts of his codebase (although I'm still hesitant, see my remarks above :-D).

In what language is your bot written by the way? @trufflepig is 100% Python 3 (and quite memory demanding!)

But I am not so sure if using trufflepig will increase your profit margin, it will be quite the opposite I am afraid. In order for the Natural Language Processing to work, he is already very picky about the stuff that is allowed to become part of the training set and to make predictions on. So about 40-60 % of posts get filtered already in the early stages because of being too short or having too many spelling mistakes or just by not being written in English. So having to turn down around half of your customers might not be very profitable in the end :-D
