Personally I think Zwallets just getting a bad wrap. Perhaps they deserved it in the past but Zwallet isn't the same anymore. I love my account there.
I have 3 huge safe lists running from it - never had a bounce - never lost an email.
I wrote them in regards to some information for someone else who said well I'll join if you can get them to reply. Ha in 24hrs they replied and even admitted in the past they had problems.
My sponsors been paid 3 times. I haven't made enough yet to get paid but I am positive that I will. Thats just my opinion though I could be wrong.
Most people that complain about it haven't earned enough to get paid yet, do not open their emails, do not realize that the pay structure is always behind... They only pay for 10,000 page views per month nothing more than that. Your earnings aren't even calculated until you have been a member for 2 weeks. Same goes with your referrals.
Its all there on their site to read.
