I suppose it's a lot easier that way in the sense that you know that the same campaign rules apply to all x accounts you have - meaning the same number of posts, start and end, and maybe a few other things. Although on the other hand it's pretty stupid to do such things because someone will find out sooner or later.

I notice a lot of strange, let's say, similarities between various members in various sig campaigns, so I don't doubt at all that there are a lot of alt accounts that are milking the same campaigns, but you have to accept that this is reality - where money is involved, there isn't much honesty and honor. If someone wanted to be at least somewhat sure, they would have to do an in-depth analysis of all those who participate in their sig campaigns, but it requires time and expertise.
