Ok so some people have been spamming my php-fusion forum with 'very' long forum posts. Whenever someone tries to load the thread after they do this the page just hangs on loading and my apache uses up 20-90% CPU depending on how many people try and access the thread! I have to delete the user that made the spam messages and restart apache. Its really annoying, once it nearly locked my entire server up.

Any help and advice appreciated!

Thanks

If you're using the standard fusion forum, you can shorten the messages to less than, oh say, 1000 characters.

Open up /forum/postnewthread.php and find:

Code Download source
$message = trim(stripinput(censorwords($_POST['message'])));


Replace with:

Code Download source
$message = trimlink(trim(stripinput(censorwords($_POST['message']))), 1000);


Let me know how it works for you

Hi, thanks for your reply.

I think I found out why such spamming was crashing my apache. Long messages shouldn't crash apache but when they spam PHPFusion is not requiring them to move on to a new line, i.e. there is no max length per line so when they spam thousands of characters the length spans really wide. Thats my theory anyway, anyway to force them to go to a new line or something?

Thanks again
