It is like a big virtual speeddating event.
"dating" is a broad word to define a large group of different proposals. Badoo is a dating proposal only for fun, for flirting, for entertainment purposes, for instant gratifications, but nor for serious dating.
It is customary for men in Latin American countries, to send their Microsoft/Yahoo Instant Messenger Address to women inmmediately when chatting online or messaging (because although at Badoo it is not mandatory/necessary to pay in order to communicate with other members, chat is slow and women receive several chatting requests. A recently ComScore report had shown Microsoft's sites rank #1 in Argentina -also in several Latin American countries- slides #22 and #24)
Also it is customary for men in Latin American countries, to request the Microsoft/Yahoo Instant Messenger Address (msn) to women as this sample of other online dating site (It was AlguienAQuienQuerer, no longer exists)
And it is customary for many daters in Latin American countries to use the same nickname as their Microsoft/Yahoo Instant Messenger Address when registering in forums or dating sites.
Suppose you see the profile of a woman whose nickname is JenniferSampleCow001
you can try the following instant messaging accounts.
JenniferSampleCow001 at hotmaildotcom
JenniferSampleCow001 at hotmaildotcomdotar if she is from Argentina
JenniferSampleCow001 at hotmaildotcomdotbr if she is from Brazil
JenniferSampleCow001 at livedotcomdotar if she is from Argentina
JenniferSampleCow001 at livedotcomdotbr if she is from Brazil
JenniferSampleCow001 at livedotcom
JenniferSampleCow001 at yahoodotcom
JenniferSampleCow001 at yahoodotcomdotar if she is from Argentina
JenniferSampleCow001 at yahoodotcomdotbr if she is from Brazil
That is why sites like Parhip does not allow you to choose your nickname and shows you profiles' names with a code (like ESFN3KTG, FS0MXG3F, ES94Z3PR and so on, to avoid any person can communicate for free, without paying the subscription)
