Be honest: you never expected to be paid 0.1 Bitcoin for this, right? So the "Deal. Let's see" was posted out of impulse, and changed within 20 minutes. Besides, saxydev couldn't gain anything from it, you didn't offer him 0.1 Bitcoin if you couldn't keep up your end of the deal.
I did expect it and it was fair price I asked for something I delivered, and he broke agreement we made.
Imagine if we made deal about anything else and I spent hours doing some work for him, than I found out he changed his mind.
In any normal website for selling stuff he would get negative rating for that, and if I wanted to make a joke I would ask for much more Bitcoin from him.
Since I didn't receive promised Bitcoin, flag stays and if you don't agree Loycev you can always vote against it.
I simply don't trust this ''dev'' who changes mind and sells shitcoins snake oil.
I strongly dislike saxydev's "taint" BS service, but I don't think Bitcointalk will be a better place if we start Flagging users on what I call a temporary lack of judgement.
