I think they'll give it a genuine shot. These stalking services pop up like weeds and every time it gets some media attention they end up with significant problems not much later. dis.cool was the last well-known entry but there's been more.
If it has the same issues Lemmy does, probably not. People don't want to build an account on a server only to find out, three months later, it's run by tankies, or anti-piracy watchdogs, or any other number of unsavory things.
