They're still paying small amounts?
Sort of. The amount you can get away with is small, and declining arbitrarily. It used to be that if you withdraw just under 0.1 BTC you could get away with it - have a read of recent posts and see what the new "limit" is, I'd guess somewhere around 0.7 BTC. You'll also get hit with a (fixed) withdraw charge - in the old days this was a maximum of 1%, these days - because there's a lower limit to the fee - it'll be over 1% (I believe - I've not seen any change to the 0.001 BTC fee, but it may have been increased. The ToS still say 0.001 BTC, but you can probably take that with a grain of salt...)
tl;dr - make lots of small withdraw requests, and accept that you'll lose out to withdrawal fees.
Don't forget to thank the admin for kindly letting you have some of your own money!
Edit: watch out for "autoreinvest", too - there's a workaround for this that avoids your withdrawal requests being magically converted into non-withdrawals, and the funds being reinvested in hashing. You may have to trawl through a lot of posts in this thread to find details, however.
