We had one or two a while back. Mods were a bit swift with those before things went out of control, IIRC.
Honestly though, if Cari wanted to milk this game he would've done so at the very first chapter by just stretching out the IRL bits and then leaving the Eternum login as the cliffhanger. Maybe even add a few unnecessary free-roam activities here and there, maybe some quiz sections (/shudders) as well.
So far though, nothing that he's doing so far can be constituted as milking behavior. And if it's revealed that he is, then he ABSOLUTELY SUCKS at it.
