    I've just read the definition of 'link farm' is a site with so many unrelated links in it. Does it mean that 'free ad forum' is also included in it? You know, in many free ad forums, in one of its sub forums there is usually a forum called 'product & service' or 'post your links' where there are tons of tons of different kinds of links in it, and it makes me kinda worried.

    So ... are these kinds of 'free ad forums' included in the link farm we're supposed to avoid? if it's not, what's the example of a link farm btw?

    thanks for all your answers
