Compared with other file hosting providers, FileServe's attitude is relatively unfriendly.
They even don't want to develop a simple mechanism to warn their premium users.:facepalm:
Ask you can see, many forums banned fileserve's links without providing any reasons.
I guess administrators of these sites were banned by FileServe and experienced a very bad/unfriendly customer service so they hate FileServe.
Here is an example:

Yes, FileServe doesn't ban users for fun, but they ban users when they're not happy.
Don't think you're a customer, just treat FileServe as your important customer or VIP.
Then you can reduce your ban-probability significantly.:P
