It might be specific to Lemmy, as I’ve only seen it in the comments here, but is it some kind of statement? It can’t possibly be easier than just writing “th”? And in many comments I see “th” and “þ” being used interchangeably.

    Im almost certain it’s trolling with the AI reason as an excuse. It would have very little effect on an AI, which would recognise the character as anomalous and discard it or ignore the comment. The only other person I saw doing it replied with every character replaced with similar nonsense when I stated similar to them. Wouldn’t surprise me if it was their former account as it was a while ago and it was copping bans because of it.

        My understanding was the goal was polluting training data for AI. Not privacy and having their comments skipped. Point is AI won’t have an issue realising it’s not useful/relevant data. Worst case is minor performance issues wasted on parsing the character.
