1-2x per day is fine, the issue with vote-trading is that say instead of posting 10x per day and voting yourself 10x per day, you make deals with 9 other people who have the same stake as you that you'll vote them once per day if they also vote you once per day. This is the issue with blatant vote-trading where you're eventually self-voting 10x per day without directly doing so but not having much in common with the other accounts except for the deal to maximize. It's okay to vote your friends/other people you like and their content often but it shouldn't be a guaranteed vote no matter the content, quality or at a constant rate, and especially not expecting a vote back for it.

Thanks for your insight.
