According to the post you quoted, you are right. The PM restriction shouldn't be lifted.

But theymos has stated something else in the topic below.
New PM limits


The Max limit of PMs per hour if whitelisted is 40.
The Max limit of PMs per day if whitelisted is 120.

The topic saying that PM restrictions are not lifted has been made on November 10, 2017.
The topic saying that the Max limit of PMs is increased if whitelisted has been made on December 06, 2017 and should be the valid one.

theymos should edit one of these topics?
