This level seems to confound a lot of people, but it can be done with a little work.
To be rated 11 by a top 250 Lifetime member, it helps to be friends with as many of them as you can. If they are running a boomerang at the time, when you rate their profile, they automatically rate you back 11.

Ability points. There are some tips and tricks here.
Reset 11 - Will not add 4 points to their count, unless all their 11's are used up. I recommend you don't use this one.
Altruize or Give Points - This will give the user only 8 points, and block everyone from being able to do the 4, 8, or 12 point "Points Boost" abilities. Avoid this one too.
Shitface and Buzzkill - While only one point each, they add up. If the user is currently cloaked, vouched, pimped, and family and points boosted, you can alternate between the two and give them your points one at a time, it would take a few minutes, but there's no delay.
