Winston specifically called out Sprig and Luizeu for low activity. I
already pointed out that it's interesting he only mentioned those two by name in his post, as there were several other people who were equally quiet at the time. Afterwards, Luizeu started posting more ("how do you feel about Luiz now, Winston?"), which makes the whole thing feel like Winston was trying to push his partner to post more so that when Winston made the later
post calling
out all the low-posters, hopefully Luizeu wouldn't be there. Notice how there is no discernible ordering system at work here, and Luizeu is listed last, almost as an afterthought.
This feels pretty weak, like a distancing tactic rather than genuine suspicion. He doesn't actually articulate whether or not this makes Winston looks bad. If anything, it seems like Luiz is not accusing Winston so much as defending himself (you're a hypocrite so your argument is invalid vs. you're a hypocrite and that makes you suspicious).
I think at least one of
Winston and Cuthilius (who Internet Flea makes a good argument for) is partners with Luizeu.
