Does it help you somehow to solve problems when you spam tickets in social networks and forums?
It won't as there is a queue probably. If the issue is something easy to handle, they will probably get to you fast. If not, you may wait a lot.
Is HitBTC going to support the monero fork? I want to be rewarded the forked coins if I store my xmr, is it possible?
Unless they state otherwise, you shouldn't assume anything and stay in full control of your private keys.
