Selfvotes are frowned upon on HIVE and will (sooner or later) result in getting downvotes.

Not really sure what the thought process here was but I'd say it depends a lot on the content and other activities of said account. It's usually easy to notice what the intentions are, i.e. if they're attempting to just maximize rewards it usually reflects in their other activities too, but if it's a few self-votes here and there I don't really think we're going to have people start downvoting them due to that. There's very few downvotes occurring in general if you exclude the brainless autotrail ones.
