Hidden links embedded in signatures and in posts ...

[Niteblade]

By making the font size zero, a person can embed many, many links ... and no one would be able to tell unless they looked at the page's source.

**** LOOK AFTER THIS IN THE PAGE'S SOURCE ****
[size=0pt]SMFoogle : You can't see this !!! Spiders can !!!
SMFoogle : You can't see this !!! Spiders can !!!
SMFoogle : You can't see this !!! Spiders can !!!
SMFoogle : You can't see this !!! Spiders can !!!

Yeah, that's a shameless plug for the directory, but hey ... you know ...

Although humans won't see it in the post, spiders will see it in the source ... and the spiders will follow the links.

I can see the links in Opera.

They're not "hidden" as such, just the size is reduced (I can still see it, but in a very small font). This can happen with all forum systems.
I guess what you're asking is to not allow font sizes smaller than a particular value?

EDIT: I'm using Opera as well

If I remember correctly, there's a minimum point size for a font being used in a post, even if the user sets the size to 0.  I believe that either 4 or 5 is the minimum font size, but I could be mistaken.

Edit: It would appear as if a 7pt font is the smallest possible font size that can be used in a post with the [size] tag.

A user could on most browser set a minimum value for text size.
SMF could as easily add some checks to make sure the size doesn't go below X where X is a number choosen either by SMF default or Admin setting

[Niteblade]

Opera, eh? I'm using FireFox, and cannot see them in the post.

[Skhilled]

I can see them with Opera as well but not with FF. I can see VERY tiny, unreadable text using IE7 with clear type on or off. Almost like a line with a few bumps on it.

Hmmm, being able to set the text within a certain range would help. At least, until FF and IE can come up with a fix.

yea this topic needs to be adresses because for all u know ur board could contain 1000's of links to illegle sites and other sites which could result in ur google ranking and stuff goin down the drain

[Dannii]

I've never seen any bots smart enough to do that. In any case, it wouldn't change your sites ranking.

[Gobo]

yea actually most search engines dont even index SMF styled topics so no biggie really

[Dannii]

They do but that's not the point. Outbound links don't impact on your page's ranking. Only inbound links do.

[Gobo]

well i dont really know much about much
but i do know that if i catch people on my forum with hidden links they are gona get the spanking of their lives!

I've been trying to figure out how to only allow sizes above 7 to be used. I've been playing around with the regular expression (PCRE) used to validate the size used, and I can't seem to get it to work as I'd like it to.
Here's the line in question, from Subs.php:

Code Select Expand


'test' => '([\d]{1,2}p[xt]|(?:x-)?small(?:er)?|(?:x-)?large[r]?)\]',


Basically, it says "Allow sizes if they're one or two digits followed by px or pt, or if they're small, smaller, large, or larger. It's fairly easy to only allow 2-digit sizes to be used (this is still a viable solution if you don't use small font sizes:

Code Select Expand


'test' => '([\d]{2}p[xt]|(?:x-)?small(?:er)?|(?:x-)?large[r]?)\]',


I was trying this, but it didn't work:

Code Select Expand


'test' => '([7-9]|[\d]{1,2}p[xt]|(?:x-)?small(?:er)?|(?:x-)?large[r]?)\]',


Anyone know what I'm doing wrong? (I am guessing all this as well as using information from past experience, I couldn't really find a good PCRE tutorial)

Outbound links don't impact on your page's ranking. Only inbound links do.

Unless you're running a link farm with 100,000's of links going out from heaps of pages on your site

Would this work?


Quick Fix - Use the Censored Word List to change "[size=0pt" to  "FORBIDDEN TAG" and this will reveal all!

[size=0pt]MOO!![/size]

Code Select Expand

[7-9]|[\d]That says "7 to 9, or any number". Remove the "[\d]" and it would probably work. However thats a very small size range.... and it would also allow 77, 78 etc

[Thantos]

 ! Do not allow 0, 0px, or 0pt to be used in size tags. (Subs.php)

Well, I was trying to make it something like "Allow 7-9, or any 2-digit number"

However thats a very small size range.... and it would also allow 77, 78 etc

By default it allows all 2-digit numbers anyways

Code Select Expand

'test' => '([7-9]p[xt]|[\d]{2}p[xt]|(?:x-)?small(?:er)?|(?:x-)?large[r]?)\]',Try that.
