So came across this question today, as it happens I had (IMHO) a decent suspicion of the solution so posted an answer and moved on with my day.
Returning to the question a few hours later to see if there had been any update I see a comment from regular user Solar Mike pointing out.. well odd posting patterns from the user. The pattern is basically the same as described in a 2+ year old meta post here, the user has a generic user name "userXXXX" and posts a series of questions all in the same format of an OBD error code for a whole host of different makes and models of car and different error codes. Regardless of whether they get a response or not they never interact with the question again.
Clearly there's some shenanigans going on here - most likely a bot of some description, although I can't really work out what they stand to gain from it (maybe scraping to build some sort of OBD-II database for a scanning tool or app??) but that's neither here nor there I suppose. Ultimately this is bad faith use of the stack and of people's time.
I admit I'm p####d off here - I get that the SE model is to help subsequent visitors as much as it is to help the OP so there is still the potential for answers to this junk to help genuine Mechanics SE visitors in the future but I don't think this redeems such a dishonest start. Even if this is being done by a bot the bot has clearly been directed by somebody and that somebody is wasting my time (and that of others).
Is there an "official" stance on these? Do we just VTC? Flag for mod attention or should I just ignore?
