I have seen that a lot of members register here just to promote their website, forum or product. Otherwise, they are trying to fool with a money making method with their affiliate links. As per my observation, there are 50-100 such posts everyday here. Moderators eventually remove them but this is waste of their valuable time. Solution to the issue is that new members should be required at least 10-15 posts spread over 3-4 days before being allowed to post a new thread. Will help reduce spam.
