Hello,
I've been having a problem with a serial comment spammer lately. I've set
the throttle low, removed anonymous posting rights, been deleting messages,
even created a script to just go through and automatically change his posts.
Still the crazy bugger keeps posting long lists of link spam to my site*.
Here is my answer to this. Set up the way comments are printed so that if
too many links are included in one comment they get filtered out. I am
posting to ask if what I am proposing has any problems and is sane. This
idea requires two new site controls:
remove_many_anchors - A boolean variable. If set then any comment with more
links than specified in the next control gets filtered when it comes time to
print out the comment.
max_anchors_per_comment - The maximum number of links that can appear in a
comment.
Here are the sql comands to create these two new controls:
INSERT INTO `vars` (name,value,description,type,category) VALUES
('remove_many_anchors','0','Set true to remove excessive anchor tags in a
comment.','bool','Comments');
INSERT INTO `vars` (name,value,description,type,category) VALUES
('max_anchors_per_comment','4','The maximum number of anchor tags that can
occur in a comment. If more than this occurs then they are removed if the
remove_many_anchors variable is set.','num','Comments');
The idea is that whole comments are stored in the database and only filtered
when it comes time to print them. That way if you want to make a change
after something is posted the original post is preserved. So this is
independent of the data in the database.
Finally, the following code must be added to Format.pm:
206,220d205
<
<
< # Check to see if we should check for too many anchors
< if ($S->{UI}->{VARS}->{remove_many_anchors}) {
< # We need to check to see if too many anchors are defined.
< my $de_anchored_comment = $comment_text;
< my $num_anchors = $de_anchored_comment =~
< s/<\s*[Aa]\s+[hH][rR][eE][fF]\s*=\s*".*?"\s*>//g;
< if ($num_anchors >
$S->{UI}->{VARS}->{max_anchors_per_comment}){
< $de_anchored_comment =~ s/<\s*\/\s*[aA]\s*>//g;
< $comment_text = $de_anchored_comment;
< }
< }
<
<
I've tested this on a fake site I run for testing purposes. It seems to work
okay in a few limited tests. My question, am I missing something? Is this
worthwhile?
Sincerely,
Kel
* I tracked his ip address down to mainland China and even resorted to
changing his posts to pro-Taiwan rants yet still he keeps posting these
inane sets of links. I wish there were a way to submit an email address to
one place to insure that it gets put on *everybody's* email spam list. But I
digress...
