This story is almost the same like what just happened to me @paulag. I stop self-voting at all, no matter how big my upvote worth to me. I won the price of 500 sp delegated from my friend @sagescrub for 2 weeks, but still I just hold myself to do self voting. yes I need to grow my account but what I thing is "respect must be earned from others, not from my own.
best regards
