Question abut cryptofresh user dispaly

[svk]

The lightning bolt indicates that the user has purchased a lifetime membership, which reduces the amount of fees they pay (through a reimbursement mechanism).

Lifetime fees are simply the total amount of fees paid by that account.

Hi,

I'm try to figure out some user info in cryptofresh.com.

Some of the user have lightning bolt icon near the user name. What the meaning of it?

In the user display page the is "Lifetime fees paid" data.
User who did't pay lifetime fees have some value there ?!
like in this link https://cryptofresh.com/u/mostar
The value of "Lifetime fees paid" is diffident  between user?
