I’ve wondered the same thing, Laz.
Which means we likely have our answer.
I just tested out the brute-force method. I was able to attempt 15 manual tries in about 2 minutes. If I had a brute-force password cracker program, this would be child's play, to crack a password.
I have noticed several names posting I didn’t recognize. When I ping the name it is a long time account that hasn’t posted in 10 or 12 years. It makes me wonder.
Perhaps accounts that are inactive for five years should be sent an email and if no response is received then deactivated.
I’ve noticed curious postings and I believe there is something more going on here.
I’ve also noticed what to me at least has the appearance of AI generated responses.
