I am getting concerned about multipool being on this pool in this environment.

As a pass through of other miners, multipool could be 90% block withholders and we would never know.  And they make an ideal cut out.  Who am I to sue if it turn out they are collecting rewards that are rightfully mine?

I am all for bitminter growing, but I don't like the sudden appearance of 20% of the pool from a group that doesn't deliver a block solution for weeks.

Let's have a serious discussion about the merits of allowing pass through accounts.  What is the up side of having them on bitminter?  And how long do we allow them to collect 17% of all rewards while their history has them contributing a statistically unlikely amount themselves?
