I moderate (well not really, since discovering MN but they haven't demoted me yet) another forum and there was a poster who was exactly like Gabby. He stopped posting a couple of years ago but still sends me interesting PMs from time to time. He's in Long Island (I can look at IPs) so I know it's not him but the similarities are quite uncanny. Mostly harmless.
Don't mind the occasional deliberate wanker here as they tend to be shot down quite quickly, especially the MRA-types. People who hit and run are annoying but easily dealt with.
The serious trolls, DM etc are very problematic for all concerned.
Top of my list of twats on the internet are my Dad's expat brother and third wife. My Dad doesn't have a computer or internet connection atm so I have a gmail account for him which I have to access from time to time. The absolute shit they send is unbelievable.
I have to play Daily Mail Bingo when they come to visit in order to stay sane; "it's the benefit bill!", "immigrants who won't learn our language", "our winter fuel allowance isn't enough to heat our Spanish swimming pool", even though they only declared a tenth of their income for thirty years when they were in the U.K and fiddled left right and centre!
What were we talking about again?
