I believe TS shaming to be just as prevalent as it was in the 90s. Perhaps even more so, because instead of "oh they write smut" at all, now it has morphed into "don't trust that player with that plot/bother to RP with them, they only care about TSing" and it makes access to plot and activity even more curtailed (since now there's mostly other-player STs rather than staff run things).
The OOC defamation stuff is just really toxic on games, always has been, but now that there's been a change to a need to rely on the goodwill of other players for any kind of non-social play. So reputation and goodwill is arguably even more important than it ever has been.
