I realise that everybody has the right to vote however they like, but there has been a pattern of very suspicious upvoting recently.

This question is 3 minutes old and has been upvoted once already, despite being clearly not of any decent quality. I've seen the same pattern quite often over the past few weeks, but without access to voting data (duh) it's hard to demonstrate after-the-fact.

Do mods have access to voting data? Can they determine whether the person who upvoted on this question has done the same thing as a pattern lately? Perhaps abusing the system whilst going for a voting badge?
