They didn't know what ED was, they didn't lock the contract in the ICO which allowed ICO buyers to instantly trade it before ICO ended
This was the biggest mistake on their side. I was so shocked that you can trade PLR on ED even though presale tokens weren't available at the time
Yep, preico tokens were locked but ico tokens weren't, even SONM were competent enough to get their tokens onto an exchange (no offense SONM).
