PayPerPost or an exercise in futility

I swear, today PayPerPost drove me bonkers.
OK, it usually has this effect on my, but today it reached the climax. I was reading the other day about a trick to get a freaking opportunity: refresh very often.
As in, verifying the opportunities once a week- as I do- won’t do the trick.
And some guy offered even more than the informal advice, it gave a step by step guide. Curious?
Well, let say that the first step is a must have one: Firefox.
Switch as fast as you can from IE if you are still using it. Now, while on Firefox download an addon by going there:https://addons.mozilla.org/en-US/firefox/addon/115.
Next step: set the addon to reload the page every x-freaking seconds and voila!
As in NOTHING!!!!

OK, OK, calm down, take a deep breath, count to ten, chant some mantra (the mantra of compassion preferably, as in compassion for your struggling soul) and take a zen approach to the whole PayPerPost experience.
It’s not working! Not for the idiots like me, who are not able to glue their asses to the chair and stare at the computer screen without blinking, because if you blink, somebody may steal the opportunity from under your nose.
It’s for the same category of stay-at-home moms, with time to burn and neglected kids.
Because nobody, as in NOBODY, can convince me that if you have to stay in front of the computer hours and hours at a time, you will have the time to look after your kids. It’s freaking impossible.

Today I tried the experiment: for three hours I refreshed the opportunity page almost every 2-3 minutes. Well, OK, I admit that I had to work something and for about 10 minutes I have not been able to check the page.
You know what happened? Every time I reloaded the page, the opportunities were already taken!!!!!!!
Something must be freaking wrong, there must be a pirate software, used by some people to steal this opps. Or some inside information regarding when a new opportunity is going to be posted.
Seriously, there is no other explanation. I have seen new opps showing up already in gray (as in reserved) in between 5 seconds span. How is it possible?
Actually it may be an explanation: only one of a kind opportunity. Especially the ones paying $50. Then I can understand that it can be grabbed by whoever has the fastest internet connection. My DSL does not seem to be the fastest one.

I gave up. I have refreshed the page for 30 minutes, every two seconds (I was on the phone and kept clicking on refresh).
Nothing happened.
It sucks big time!
