They claim its to poison AI models, but its been repeatedly proven to them that it doesn't work. They also claim to want to bring back older English symbols like this too, not only has it been pointed out they're using it wrong many times, but in my case and some others, it just makes their comments an illegible mess. Ultimately they're just one of those edgy Lemmy personalities.

Its the old version of the digraph TH, and some are trying to revive it. I find it pretentious and cringy, like that guy I once knew who insisted on pronounced Schedule with an "SH" sound.

The thorn character represents the two TH sounds in English. THought and THose.

They are trying to bring it back, I guess. Odd but fun.

It’s a letter for “th” called thorn. I’ve only seen it on old tombstones.
