Yes, I know overall these sites are not scam sites. But how do we know that internally they are not posting fake jobs so as to use more of our credits so that we have to buy more? I get this feeling because I really think/want my reply rate for jobs to be higher... especially when I look at others who have bid on the same job (sloppy looking profiles from overseas). This was all just a thought and not trying to start a discussion about effective ways to improve efficiency on these sites. But the user would never know if this was happening and there is much incentive for these sites to do it!!!
