I understand you want your thread in top pages to make anyone will be visible to view your thread, but you shouldn't cheat by paid shills to bump your thread since it's suspicious and bad way of marketing in this forum. Your account could be tagged if someone caught you paid shillers.
And for the most post paid shills / account bumping services don't do anything because none of them have any bumping power.
And they are well known, if you use one people will know.
You need to attract good members to comment on your post / bump it.
Have a bit of a read here before doing anything:
