You can make accounts but they will have 1 activity and be obvious shills. My accounts are all member at least.
Many discussions are easy to find relating to ethics and ''forum legality'' of multiple accounts.
How will your accounts attract my audience? If they were to be attracted, they would get attracted without your service and if not then i will only have only your posts on my thread, and the question is, what will i do of only your posts on my loving thread?
