@Dave-and-Deb0, I flagged a few on the anectodes forum, but I have pretty thick skin. A few got the threads removed, mostly when they were insulting everyone and got flagged by several persons via the profile flag. Those profiles stay, but they don't get bookings over time, maybe because they are just crazy and insult their potential guests too.
I got one person removed in record time with a message from trust and security team, that it was a phishing attack. He contacted me via a fake inquiry, pretended to be a journalist, for channel 2 of French state TV. Not very likely, maybe a freelance journalist for an obscure Internet TV. He tried to get offline contact, but did not try to smuggle a link through the censor.
I reportet some service spams but they were not always removed or not so fast (I don't check them regularly either).
I read somewhere that the spam flag prevents further messages to go through, but not sure where, maybe it was only an opinion. But it seems to work.
Over the years I had a few guests who turned ugly when they canceled after check-in and did not get refund or caused damage and had to pay. In those cases, CS was very helpful and as soon as I told them, they blocked all further messages (and handled further details in case of need)
These profiles stay, checked 2 of my 3 really ugly ones, no more reviews on them. (Never checked the guest causing the big flood, 18 month later, I still can't)
Maybe in February for the FB group. When I'm in Sète where they fold back the walkways before dusk in winter 😉
If I get my accounting done till then ;-(
