Is there any risk.......................

I am scared by all your replies...

There is no such thing as 100% safe if you use nulled vb.
If you want 100% safe, you may:

1. Forget vb. Use free or open source forums. There are plenty of them.
2. Buy a vb licence so you can use it worry-free.
3. Leave if you are living in a country with strict copyright laws and good law enforcement. Go to a country which won't bother you about copyright infringement (eg Russia, China). [Well theoretically you will still be in trouble but the government doesn't enforce the law nearly all the time]

I am afraid of the underlined thing? Please help.

I don't really understand what you are worrying.
What underlined thing are you talking about?

Man 100000000's of people use nulled vBulletins. How are they going to sue/jail that many people? They won't. They will just get your website shut off most likely.

Well the poster asked if there is any risk. The answer is yes since you can be one of the 10000...
Someone get jailed by uploading files on the net.
Even if you don't get jailed, you may be sued for compensation. Who knows?
