My main account has been banned from posting for 30 days and my main forum thread has been deleted.
I didn't receive the clear explanation of what was the reason for the ban and who to contact to resolve this issue.
The exact RED message on my profile is:
"Sorry ExchangeCoin, you are banned from posting or sending personal messages on this forum.
Reason: Running an on-forum altcoin giveaway / Incentivising posting within specific threads. Ban duration: 30 days"
