I’m guilty of this when using a web browser, I’ll scroll down a page and open relevant posts into new tabs until I’ve accrued several. Sometimes I don’t get to them for quite a while so if I upvote it’s surprising how high the number jumps until I realize it’s sat there for half a day.

I try to refresh when commenting because 9/10 times someone else has already commented the same thing since the internet is dead but sometimes I forget.
