All along, I thought it was Roobet.io instead of Roobet.com.

I visited Roobet.io and it seems to be listed on Park.io (could probably be up for sale)
My question is;
1. Was Roobet.io ever used by Roobet casino before the decided to settle for Roobet.com?
2. If not, why not buy off that other domain (roobet.io) so that phishing scammers don't buy it and take advantage?
