I think the demand for this type of microearnings site (faucets, PTC, etc), with Bitcoin is just going to be decreasing more and more. With the current transaction fees someone would have to work for weeks just to get an amount of Bitcoin that they would actually be able to spend - all the while the site could end up a scam like epay.info.
I've seen some complaints against the dominant one BTCClicks recently though so there could be a gap in the market if they end up scamming. Just don't expect your returns to be too stable.
i will definitly not scam anyone. but the argument with the fees is very good,because like you said,it takes much time to cover the fees,or you have to pay at a larger amount,to cover the fees once.
