I don't really think upvoting yourself is that big of a problem. Ya it sucks to see a whale 'waste' voting power on themselves and not someone else but if you are posting original content or adding value to the platform I think you have every right to reward yourself too.

I think we have a bigger problem with people spamming, posting articles and videos without citing sources. It's to a point where I see a lower rep post a lengthy well written article with no sources and I don't even bother voting for it because more often than not someone else wrote it.
