Links in Signature

[C.Rebecca]

In my opinion, forums are communities where you share your ideas, thought, help each other out and many other things.
If you are contributing in a good way, you can build up a good reputation. If you have a good reputation, only then your backlinks can give you fruitful results.

I, personally, would never click on signatures appearing beneath spammy or useless posts.
