Yup. Its an IDN. Thats why its all a con. Since earlier this year you can register domains with “special characters”. Look closely at the “i”.
I dont know the ins and outs of IDN (crap idea IMHO) but essentially someone would have to type in http://www.gambl-.?*~!ing.com to get to that domain !
Its a big rip-off that fraudsters can exploit (as in this case). ICANN should never have allowed it to happen.
