How Firefox's Tabbed Browsing is Helping Scammers in Africa

One of the worst things about tabbed browsing is the ability to open many sites ( in tabs ) at the same time while navigating them easily without switching the windows.
The Mozilla Firefox browser has strongly pushed tabed browsing due to the ease of use it brings to web surfing. I personally see how it helps me read soo many blog articles or tutorials in the same browser. But the worst part of it all is how this our African Scammers use it to open many "classified ads " sites to post same spam on all sites. You need to see how they post about 200 spams in an hour, just with the help of tab browsing. What will happen if they put in 6 hours ? If my maths is right, one person will post 1200 items in 6 hours. Usually they have internet at home, just imagine the spam they can be posting, and still captcha cant do anything.
See how Firefox from the Mozilla foundation is helping them spam classified ads sites.

No wonder www.kerawa.com was already complaining about spam.

I went to a cyber cafe here in Buea( Cameroon ) the other day, and I saw a young boy of about 18 years working with the Mozilla firefox browser on a pentium III windows xp system with about 128 mb ram and he had opened about 50 tabs on the same Window. Beside him I found guys complaining about the internet connection being too slow [ what could be the cause of the slow lines ? ].
Actually with soo many tabs open, and about five such young guys in that cyber, then no body will be able to use the internet anymore, just because five computers are already consuming the bandwidth required by 50 computers. What will the others use now to read their yahoo mail [ ofcourse 50% browsing in Africa is yahoo mail and 40% is manual spamming ;) ].
I personally think if Mozilla foundation can put a customisation module on Firefox where a cyber cafe admin can set the number of tabs to open per window, then this issue will reduce the number of spams per day from scammers in Africa. And I think it will help to ensure the proper netiquette to be practised in African cyber cafes.
This will prevent scammers to open many tabs and copy paste ads into many classified sites. Remember even Captcha cant stop manual posting, so we have to do something about this multi tab browsing abuse.
To conclude I strongly blame the scammers for using Firefox to send their spams faster, I love tab browsing, but I want the world to see how Africans are using it for the bad side. And about Mozilla Foundation: they are not actually the ones promoting it, but people always devise bad things out of good ones.
