Cysec could handle things better, but it does sound like they are conducting an investigation. If everyone complains, although IronFx may not be directly forced to pay traders, this could result in a fine proportional to the amount imporoperly taken from traders. If that happens, IronFx would likely try to pay at least some traders to help reduce the fine.
Plus, a Cysec ruling that IronFx improperly took money would make it much easier to win a lawsuit against IronFx.
Don't forget to visit Wholesale Forex Complaints and follow the instructions in the IronFx thread.
I would add a recent circular made by Cysec about bonus conditions. it looks like they are working somehow on theese kind of matters.
