125 posts in a week? I find it hard to believe. But can that be possible to do every week by one person and the person will not go blind from watching the computer screen for that number of hours? If it is not a bot doing it or magic I do not know what else can. This can also be why we find shit and off comment posts from high ranks who are into this because they want to complete the weeks count.
It's hard but not hard too if they do it using proper time management. In another post I was doing some calculation for eight hours of work. And per hour you only need 2.25 posts to make which is not hard job to do if one is taking it seriously as their day job. But they will not have a weekend LOL. Even missing a day means they need to fulfill the current day's post with previous days one too. This makes it hard.
I used to make a lot of posts in the past but it's only possible when you are enjoying your time in the conversations. However, still making even 60 to 70 posts a week is difficult.
One way to maybe find out the truth would be for admin @theymos to look at the IP logs from that time and compare the IP logs of all involved accounts. However, in all my time on the forum, I remember only one case when something like that happened and it was publicly talked about (@bill gator case).
I doubt theymos will do that unless it was involving a huge scam that could effect the entire forum reputation. There was a case long ago, I can not remember the year clearly, it was sometimes in 2012 to 2014. Besides, having alt account is fine. Some prefers to publicly admit it and some do not. Both have their own reasons.
