I don't self vote (intentionally, sometimes there is a self inflicted vote via curation trails) at the moment. I started off self voting (probably like everyone on Steemit), but in the end, I figured the long term investment of that vote would be better spent supporting others in the hope that it would come back. Even at this stage of development, a self vote at full power is worth 5 cents, so it really doesn't matter materially one way or another. However, if I can use it to reward comments on my posts or use it to reward other's posts, then I think the return readers and comments are worth more than the self vote.

I have no problem with with people self voting, and don't get me wrong if my vote was worth 10 or 100 euros at full power, I would surely be doing it!

I don't think it needs to be written out of the code. But I do have a much larger problem with self voting on comments.
