Well this is more a matter of pride and being concious. I used bid bots a few times, and stopped using them to receive actual votes from people. However (and despite making decent articles) people won't vote unless you made networking with them before. On the other hand, some people I know used bid bots when the Steem price was high, and now they have a huge amount of SP and their investment intact (at that time you received the same or more amount than you invested). I kind of regret not using bid bots anymore, because at least I would have received some SP.
People who made a lot of SP with bid bots are happy with their earnings and we are worrying about being politically correct.

Anyway, I'm one of these politically correct people who don't do things just because it sounds unfair. That's why I probably will never be rich.
