OMG, page 12 now? We were only on page 4 when I last checked in a few days ago!
I've heard no more about the Appen China thing.
Data breach at Appen makes sense, I wasn't aware until now. I did notice my junk mail folder is suddenly full of "Test and keep X product", I wondered which site was responsible for those. For all I know they could be genuine, but I'm very doubtful.
I got started with matched betting, started up with a bookie and deposited £20, placed a £5 bet to trigger the free bet, with the intention of using the rest of the deposit intermittently so as to appear as a "real" bettor. Actually won a couple of other bets, so am currently about £40 up! I bet on one with fairly high odds, as a sacrificial bet expecting to lose, but it won. Result!
