So, I posted this (every character between the quotes):
" /, ,| ,|
/| /( ,' / ,//
\`( |/ /,' (,/ |
\ \ ` ` ` /--,

'-.____________` /
[ \@, :] `--,-..-

\ / __ ./

\ -. `,' (333
3`--'' \33.
,333_) /mm33333:.

':#:ctr3333''#####\

/:#:|:::\|::::::|:(

/:#;/:::::<::::::|("
into the 'Website Title' text box on my profile's editor and got a 403 error page. Specifically:
"Forbidden
You don't have permission to access /forum/index.php on this server.
Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request."
Whether or not javascript was enabled did not make a difference.
This occurred when posting the same thing into the 'Website Url' text box as well.
While I realize this may be nothing, I know it at least means that your server is *not* simply cutting the end off of the string I gave it, and setting the remaining characters to my profile's website's title/URL.
