Leeching.net Accounts keep getting hacked?

[Nexal]

So I use the Rotmg account creator tool here on the forums and I use them to make multi box accounts, of course, and I just checked and as of now I have lost a total of 8 multi box accounts, with items on them. They continue to be hacked and have the items stolen, why exactly is this happening? Both accounts have been shit thankfully, but its still annoying as hell. I know its easy to recover accounts using leeching addresses, but I've never shared the emails with anyone. Someone just getting lucky with putting emails into the account recovery screen or what?
