Next week, at the end of the month, if the pattern holds, we will see major estate land owners canceling more sims, and then within a week, the exact same large land owners will start to add more sims again. This pattern started shortly after last October when Linden Lab allowed anyone to buy an estate sim without any set-up charge for a couple of days, which enraged many large land owners.
I have a theory as to why since last October, large estate land owners are dropping sims at month's end, and then picking up more a few days later. But I won't say anything more until we see this pattern happen once again. Stay tuned.
