The nomination does not guarantee a spot on the list.

Each nomination will go through an evaluation process before being added to the list, while TrendAI™ might contact you for information, but we have no obligation to keep you posted on the progress. You can also nominate a server to the blocked list through IP Reputation Lookup.
