Well, it is true that Paxum.com has a long history (>10 years, I think). It's a Canadian branch of the “Paxum family” (Paxum Bank, Paxum, Paydek... maybe something more) and perhaps the most reputable from it. I heard a number of negative stories about Paxum Bank and Paydek, I do not recall much about Paxum.com. (But I can imagine that they are confusingly interchanged / not distinguished well quite often.)
They accept high risk businesses and their fees are higher than with cheap EMIs but I would definitely not call it a robbery.
Having said that, I would perhaps trust a little bit more Verifo or Bilderlings (as we consider possibilities for opening an account for high-risk business) – because of the possible connections inside the “Paxum family” that are unclear to me.
