Ok
I've seen many forum puts 50 as threshold to put signature. Why is that ?
I don't want users to have signature unless they have more than 50 post.
I saw a forum member selling signature spot and he is the top poster in that forum. But he has many junk/off-topic post.
Which is better thing to buy from a popular forum member ?
I've couple of offers to promote my site. One user is offering blog comments backlink and another is offering me forum signature.
I know the signature or number parameters they accept are different. But that is a trivial difference.
Allowing image signature can harm my forum in any sense?
What do you mean by fake signature in terms of forum signature?
A forum signature link is manually made by the owner of a site (usually) and this is not natural. Google states that any unnatural link is blackhat SEO.
Are forum signature links good for link juice?
