i can provide you members for your forum or site, as many as you want. Post your offers below. Payment should be paid in advance in alertpay. Offer available for the first few members who bid for the highest payment per member provided.
what promotion methods you will be using to gain signups? You know it would make difference in genuine signups vs. some "piad to signup" or if you sign up yourself using proxy and different email accounts..
i would use forums, the sign ups would be real, to tell you the truth i don't know till date what actually a proxy is, i don't have time for making hundreds of email IDs and then signing up into a forum. its your choice whether you like paid sign ups or not, i can however make every member to make the required number of posts you want but for that you have to pay high, lets suppose you ask me for 100 sign ups and 5 posts from each member, is it possible for a person to post 500 posts by himself with different thoughts. Any ways its your choice. For a newly made site you actually need this.
Paying for members? =/ If you have to pay people to post at your forum, you're doing something wrong.
