I’d assume he’s got link pings turned off, because otherwise he’d get pinged every time someone linked the TGR post.
He has a suspicious habit of appearing in threads where he’s quoted, so he might have quote pings turned on.
That said, vetex has never got upset at someone frivolously quoting/replying or linking to his posts, so even if he has those pings on I don’t think he cares.
Just don’t spam it for the sole purpose of pinging him I guess.
