phplinkbid sites are still profitable IF YOU DO IT RIGHT! its easy enough to call out the cheaters I can show you how if ya need... plus the script is very affordable and includes free lifetime upgrades and phplinkbid boss Tekime is a very nice fella. Google doesnt ban scripts that just ridiculous just take a look at yacg those sites still get indexed and rake in tons of traffic until the domain gets banned.
That's kind of a triple post actually? It happens... I have had it happen on more than one occasion. Its generally a forum issue, ie., forums are down or unreachable when I hit submit and it ends up submitted twice. Let a mod know and they will delete the double post. Or you can do it yourself.
I don't thinks it's Profitable Venture. Because there are so many free directory available on the net now a days.
