Staunch loyalists or anyone just being civil at times and on the right venues are not really hugglefesting, they are just being polite/diplomatic.
Hugglefesting mostly comes from character specifically designed to get along with everyone and actively trying to do so (to the point of trying too hard), I think.
I also think that a lot of these use the Summit frequently. But I do not see anything especially wrong with that kind of characters. After all, that's a little like IRL, somehow...
One thing that I find extremely hugglefesting on a personal level though, even if not done intentionally, is people calling my character by her firstname. It does not happen only on Eve, but in most online roleplay venues I have been part of. I am not really sure why, maybe OOC bleedover - except for characters specifically designed to be dramatically friendly/buddy/familiar - but even strangers address to other characters by their firstnames. It tends to sound quite wrong to my ears. I just feel the need to ask if they know each other or who the hell do they think they are. Well, my character couldnt care less, but she still finds it a little confusing. Me on an OOC level, extremely confusing, and maybe wrongly, quite buddy-buddy.
