wp-linkbuilder

It's not useful at all, all details only PRO version, and another thing, it records pings too, received from vary testing sites. Uninstall it.

We installed this plug-in about three weeks ago. As soon as it was installed we started to receive between twenty to thirty new backlinks per days. These backlinks were all spam bot backlinks almost exclusively from Russian and Ukranian sites, many of them pornographic or links to 404 pages. We deleted them every day but the next day a new batch would appear. We sent three messages to WPLinkbuilder support to ask if this could be resolved and not one of these was even acknowledged. We then deleted WPLinkbuilder and since then we have received no more of these spam bot backlinks. Unless you want loads of spam bot backlinks which, presumably will damage your Google ranking, and no technical support, you should avoid this plug-in.

Just yesterday I installed wp link builder on two of my blogs. Meanwhile it detected 17 backlinks on one site, and 2 on the other one. – Support replied within 2 hours – No conflicts with my other SEO plugins Keep up the good work!
