How about having a poll for how many 'strikes' (questions/answers removed) an AB member is allowed before they are 'out' (banned, and I mean permanently - no creeping to the Eds)? 'Obvious' spammers would still only be allowed 1, of course. I'd go for 6 - it would allow the odd indiscretion, but hopefully get rid of the guilty 'frequent posters'.
Yes, I know, they could easily rejoin under a different username, but they would lose their 'cherished' one.
I've never had jobs where I clock watched until my last job, which was boring. It's health that has let me down for the last 10 years and the loss of being able to get out and tackle our piece of land and be out and about in the countryside. I'm really not an indoor person.
