3 thread rule - no more than 3 thread in the 1st page
banned multiple user - using more that 1 account in a thread.
Using the 2 rules plus "equal opportunity of exposure" I come up with a scenario.
Considering a person with multiple accounts.
account1: 3 threads on the first page
account2: 3 threads on the first page (items are the same as account 1 but the title and description might be different)
that's 6 threads in the first page for the same person(2 accounts).
is that OK?
