As the checking is quiet rudementary, this can be easily tricked. For example write the reciprocal URL as text (i.e not a link) and the checker accepts this. Also on site where the code as been changed to look for a HTMl link this can also be tricked by using the same text colour as background colour so the link will not be available to the visitors of that site and will not generate the traffic as expected.

Have you thought of ways to stop this, as people will try anything

Hello,

Yes, the system is very basic. I will probably add checking <a href > tags in the future, but as for same text color as background that would be a VERY difficult task (if not impossible) and will almost certainly never be added as LinkMan would need to "understand" CSS scripts (internal and external) and all the other techniques. Even huge well developed search engines like Google have major problems and little success detecting such things.

Solution: Take that 1 minute of time to review each new link manually :wink:

Regards

People can also place there links dozzens of times with just one link or tekst or wathever back, or link back on a page that isn't reacheable by clicking through their site for normal visitors(by making a special page for this kind of links). They can place a No index tag on the website were they link to you so google etc doesn't index it.

and maybe you can somehow add an ip blocker in admin so you can block people if they keep spamming.

never the less exelent work.
I'm looking forward to your updates

thank you very much.


sorry for my crappy english

I am also getting this problem. The reciprocal links appear to be on special "standalone" pages that can't be navigated to through their main site. I'm not sure whether to allow these types of submissions. It seems pointless since their visitors (and perhaps even search engines as well) won't ever see the page. Do other people have this problem and do you allow this?

To be able to handle this correctly the script would have to browse entire websites (possibly hundreds or thousands of pages) to see if the links page is linked normally or just a hidden page.

An easy work-around is to set a minimum pagerank limit for the reciprocal links page. Set the limit to 1 and while you will be blocking some new websites that don't have a PR yet you will also be blocking pages that are hidden from search engines.

Thanks, I have now set the minimum pagerank to 1 for the reciprocal links page. Hopefully this will improve the quality of submissions from now on.

Although the above works fine, I guess another possible solution would be to require that a link to the reciprocal links page exists on the submitted website's homepage i.e. the URL already submitted. This way, the script wouldn't have to search all of the website, it would help ensure the links page is prominent, and new websites without PR yet could still take part.

If you monitor the incoming link requests you can check them by hand, just make sure you have the moderation in effect. then just do not allow any site that does not meet your rules for signup. Thats the simple way if you do that they cant get there links up as you did not personally ok them. So then you can delete them and block the site if you like.

In my opin this should work fine.

The latter is not worth the effort as most pages use css so you would need to check there css file woulddnt be as easy or worth while, just moderate your links and all should be fine.
