I don't know how ingenious it is, but I prefer consistent daily pressure by using brute force.
For example, I use a traffic exchange / safelist combo website, that increased one single click I make by 100 credits every day. For example if I click that spot daily for a month, I earn 3,000 credits a day for that one click. Of course there are other ways to earn credits, so I spend about 30 minutes every day earning them to post my own ads.
Yesterday I bought a high profile ad with the 500,000 credits I saved up this month, so every member that logs on today will see it and they have over 300,000 members.
The best part is, it's all up to me
