Google search algorithm is fine tuned to read the text surrounding your link and if it sees just an anchor link (with no surrounding text), it may be considered a 'spammy' or suspicious backlink used for the purpose of manipulating search engine rankings. Google has recently started to serve up site penalties for such backlinks.
When backlinking from forums, you may want to take the time to expand your signature line to include more than simply an anchor text link. Maybe even including a full description of your site and using as many characters or words as allowed for the signature line, rather than numerous keyword backlinks.
Please talk about other ways to use the forum signature line option to promote your forum or blog and for better SEO/search engine ranking.
