I'd hardly say it's dying a death I think if you exercise caution and common sense there's still good fun to be had.
I agree with NIK I'm not into paying to view private galleries, there are any number of free sites where you can access photos porn clips and webcam performers if that's your thing, so why pay on AW?
Check feedback, if it's hidden there's usually a good reason, look at the profile If a lady makes it too difficult to see her (like requesting me to have a direct chat, viewing a private gallery, paying a deposit) I DON'T BOTHER.
I think any experienced punter should be able to spot when something just doesn't seem quite right.
I don't use the alert system so it hasn't affected me but I don't see any viable alternative to Adultwork so I just make the best of it. If I happen to have a particularly good punt I leave appropriate feedback on Aw and elsewhere to let others know and it's the same with a bad punt.
Yes there are scammers on AW but word seems to get spread and you can't get away with duping people for ever so eventually these ladies will see their revenue decline I guess!
Personally I'd sooner have AW there as it is (warts and all) than not at all. It can be annoying at times but we'd be worse off without it in my opinion!
