To put it short:
Trialpay is very scammy.
Trialpay pays Urban Rivals
Trialpay scams Urban Rivals users CONSTANTLY
When weighted the impact of PR hit by being associated to Trialpay is less than the cash flow paid by Trialpay to UR.
Greed wins justice. Urban Rivals is associated with obiviously fraudelent and repeatedly bad-behaving partner.
What you can do about it?
Much nothing - because money wins.
Here in Finland we have some decent laws against bad advertising and some basic recognition of consumer rights.
By Finnish standards Trialpay could be considered to have broken trade decensy rules repeatedly, upto the point where such company managers could even be punished to the jail for few years after receiving several warnings and penalty payments.
Too bad TP is not Finland based company so we cant touch it, in less developed countries - ones that have a bit more corrupt business/legal model - this kind of business is still "OK".
