Hi Shaun,
I used them quite a lot, I started by blocking all countries but China. Eventually I hid my profile and picked and wrote messages to selected ladies, although I did get some interesting smiles as well.
I've made 3 deeper contacts which didn't work out because of chemistry/circumstances and other things, one of them is a penpal now and we chat occasionally.
Some other one's were translator run profiles, communication with them proved to be cumbersome, slow, I even got standard letters addressed to me, except they got my first name wrong :icon_cheesygrin: You can spot them by their logon time mostly, they only "open" during business hours.
And of course there are scams, but not that many on Chinese profiles, so blocking the other countries helps. Reporting a scam usually caused that profile to be deleted very quickly, they seem to have a decent moderation team on there.
If my current quest doesn't work out, I will use CB exclusively, Chnlove is too full of surprises for me. The only downside is the smaller number of profiles on CB compared to Chn, but it seems to be growing.
