short of knocking round everyone in the local area what better way to find a decent trade?
... especially with the reduction in the number of newsagents with cards stuck up in their window.
Also
These are all moderation issues ...
absolutely. However, a moderator and founder of a (previously public) local facebook group near me got so fed with the verbal abuse he was getting because of his insistence that businesses that advertised (for free) be local (and, this is guesswork, the lack of support he got from other moderators) that he walked. I was never a member, there was so much hostility.
Example: There was a story on a local news website about a school girl being attacked and requiring hospital treatment. Member straight in there, blaming the school 'it's that school again! Can't keep control'). Some others pointed out that the school was named because that was the one the victim attended, the assault happened after school and the assailant's school was not named (I'm not sure it was known at the time, but it wasn't the same). Member back in, why hadn't the teachers done anything about it. I have seen teachers patrolling the road the school is in and the nearby parade of shops as well as the bus queue, but this took place some distance away, over a major road and a railway bridge for a start. Member still not satisfied.
Example: The 'when does (the pub that serves food) open'. When someone suggests that (as in #13) that they contact the venue, they are descended upon, people should be helping one another.
Example: A member wanted to know how to get to a particular supermarket by bus as they had applied for a job there. Member then issues out of date advice, initial stop had changed, route now stopped short, and has limited hours of operation* (very unlikely to get there by 9am, for instance). Another member suggests train followed bus for speed and frequency but is shouted down by the initial respondent and others, who
know these things.
Some of it was funny, may still be, its gone private now with some of the old mods, potential members are warned that if they are easily offended to stay away so I guess its like the wild west.
These groups are what the members make of them, it is just that I see no benefit from a group that oozes aggression and misinformation (in my opinion).
* - I knew these things as I had a copy of the timetable and I used the route.
