Now a days many of the forum administrators are enabling  nofollow tag to the signature links added by the forum members.  In their point of view a dofollow forum signature or allowing dofollow links in the forum encourages the spammers and they start to create tons of links only for the promotion of their services. So at last many webmasters decide to discontinue dofollow forum signature.

 The consequences are actually suffered by genuine members because of some spammers. Actually most of the forum participants except a few newbies are really interested in the growth of the forum. They are actually contributing content  or new ideas among the community and that will create  hot discussions.It is like give and take policy where  user should provide useful tips or content to the forum  and take the forums reward(in terms of dofollow links) for their work.

Precautions to stop spams in a forum

 

There are many safety measures we can take to avoid spammers from our forums. They are:

1. Set a post limit

Setting maximum number of posts per day is really nice way to stop spam activities in our forum.

2. Set a minimum number of valid posts

We can set a minimum number of posts before activating signature links on our forum

3.  Set a minimum period of time

The member should be active for a minimum amount of time in our forum before activating the signature links.

4. Signature URL count increases with number of posts

Set different threshold for enabling more signature URLs. At first there should be only one signature URL allowed and for next urls he needs to complete certain criteria.

5. All links other than signature links should be nofollow

We should add rel=nofollow to all the URLs in our forum except the signature links.
