I once blogged about how I blocked one of my best friends on gtalk, so that we'd reserve all the stuff we wanted to talk about for real phone-conversations. Since then, I've had several hits by people searching on google for "how to find out if you have been blocked on gtalk". To do them justice, I will explain in this post how.
Although Gtalk won't let you know if someone has blocked you, eventually, you will find out. For e.g. if A is an annoying bugger who can only think of asking me when I'm getting married, and I don't want to deal with him, I just block him off. and think all is good. But, A might know B, who's also on my list, and they might be having a conversation online at the same time I'm talking to B. B casually mentions, "Why don't you ask tgfi, she's online" and A says "tgfi is online? Not on my list!". Heh. Even worse, is if A sits right next to B in class, and B has that green button lit up on his gtalk list next to my name, and A doesnt.
So, all it takes is one common contact and a lucky moment. Or else some clever sleuthing, which, I am sure you are up for if you are googling "how to find out if i have been blocked gtalk". Yeah?
Admittedly, I secretly enjoyed the moment A discovered he was blocked. :)
