We have a very simple and straight forward policy on spam. We don't tolerate it.
This extends to self-promotion in posts which includes the signature block that each user can set up via their profile.
And please ensure that your posts as well as signature do not contain any text that can be seen as a method of earning from other forum members.
Examples of this would include information to any type of associate, affiliate or referral schemes.
If your signature currently contains any such text then please amend it at the earliest opportunity.
Thanks.
