So my advice is, wait for that person to support a scam and then flag him as supporter of the scam as i did with the scammer nutildah
I'm sorry to hear that happened. Yes, from my own experiences with that person I have them on ignore as they tend to high-jack threads with their obsessive startling rants. As you can see, they hadn't posted in this thread prior to your mention of them, so they are either stalking references to their own name, (if they aren't stalking your posts).
When did your encounter with this person occur? As you can see from this quote:
Have just recalled that user
nutildah offered their
own account for sale a while ago as recently as the 23rd of July, 2017.
BPIP is inconclusive as the change of password ten times in 77 days didn't occur until 2018.
for a ten month period that account was up for sale by the owner. Take some advice - just ignore the tossers and don't feed the Trolls.
