@Pandya My activity log says I did not. I have only 1 vote on that site, it's an upvote I placed on an answer about an hour ago, which is when I noticed the weird profile.
Wait
No I didn't.
There's no reason I would've upvoted that answer and visiting it is not in my history profile.
@ShadowWizard I misread that @JasonC casted that vote so I thought it is meaningless and deleted but after @JasonC declared in his podt that he hasn't casted that vote, I realize that I was right.
