Upvotes glitch

I apologize since this post isn’t about the app itself, but rather the website.

Just a quick note. As I’m writing this, I gave myself 6 upvotes on both of my comments just by opening the site in incognito or using different browsers. No login needed, which is kinda fine, but from a professional standpoint, it would feel more solid if the website asked users to sign in before allowing upvotes, same way it does for posting.
