From tampering by what?

Use file attributes to prevent intruders from removing traces of their break-in. Both Linux and the BSDs have the ability to assign extra attributes to files and directories. This is different from the standard Unix permissions scheme in that the attributes set on a file apply universally to all users of the system, and they affect file accesses at a much deeper level than file permissions or ACLs.

One useful attribute for protecting log files is append-only. When this attribute is set, the file cannot be deleted, and writes are only allowed to append to the end of the file.

How can I set to the append-only under Linux ?

I didn't even consider a security threat in a forum. Will that add to the cost of opening a forum?

To set the append-only flag under Linux, run this command:
# chattr +a
filename

Damn so many costs! Can you have some sort of firewall? Tampering with a forum would be as hard as tampering with a website isn't it. Doesn't it depend on the webhost?
