It was shown when I tried to add a friend from the original website
The fact is that this 5 $ thing is not recent but seems from 2015, while my Steam was working fine until march
Also, this only applies for the "new" accounts, because my account is very old it doesn't have this limitation
In the meanwihle I made another person test his own account in Miranda (he created it in 2016 and he has payed for a game); works fine
I can understand new accounts might have problems because of this new limitation; but they still connect, while my account doesn't reach the online status at all
