Not very good at researching either but those usernames look like some quick names created by random name generator or something.
Man, it wouldn't even take that much effort as long as you're familiar with English/American names. I could probably create 100 usernames like those as fast as I could write. By the way, the only reason I included Aliceooo75 and Liamttw is because of merit linkage, not because they have similar usernames. And again, I'm not sure they or any of these members are alts--but I'm
pretty sure that some of them are.
I think they are a group of newbies who use a new trick to collect (Merit) between Alts, to reach a certain rank.
My thought as well, but I'm looking for someone to help link accounts like you did. I think there are more alts in my list than the two you discovered.
All three woke up on the same day and previously, all three became inactive within a ~36 hour period.
I tend to agree with you on that one, though it isn't definitive proof.
As for me, I'm going to withhold merits from all of these members unless or until this issue is solved, because my suspicions are too great for me to be an unwitting participant in any merit-distribution scheme among alt accounts. I've already merited some of them, and now I regret that.
