Hello List,
I've written a simple guestbook program and, of course, I get spammed
like crazy. One of the ways I am trying to avoid this is to keep a list
of keywords that, if they show up, cause the post to be rejected by
calling a function called "end". Currently, I am implementing it with
code like this:
sub process_post {
my($new_name, $new_location, $new_website, $new_message) @_;
end() if (
$new_website =~ /
info\.aadityasood\.net|
some\.bogus\.website|
another\.bogus\.dummy
/xi
||
$new_message =~ /
health insurance|xanax|ringtones|
viagra|cialis|student loans|casino|
demadex|online poker|\[\/url\]|
blackjack
/xi
);
# ... SQL insertion code here ....
There's more to it, such as a list of bad IP addresses, but the example
sufficiently expresses my point.
I was just wondering, from a regular expression standpoint, if there is
a more efficient way to implement this type of comparison. I was
thinking perhaps putting all the keywords into various arrays such as
@bad_websites and @bad_words, then looping through them, but I'm not
sure if that will speed things up or slow things down.
Thanks in advance,
Adam
