Doubtful. It's kind of the way humans work, you know? We identify people as friends, foes, allies, enemies, whatever, and tend to carry those associations from one context into another. I get why that's frustrating for someone who might want to sort of make a fresh start on a new site (and especially someone who admits to awful behavior elsewhere and doesn't want that following them around - sorry, them's the breaks), but it's just kind of the way people work.
I've been on Reddit for two years and never identified a subset of people on there as friends or enemies. I think mileage really varies person-to-person and it also depends on what users are looking for online. If you're not looking for that kind of community, or if you're looking to Hubski for information and interesting articles, the Reddit circlejerking really gets in the way.
