At the time of writing this post, minimum rank to join the company is now as low as 4 (compared to usual 8-10) as we did our half-yearly cleanup.
For future references, while our company does not have a required minium rank to join, we do clean up members who haven't driven more than half of last year twice a year (usually once at the end of it and once in summer) to lower the employee count, thus lowering minimum required rank to join (exceptions are members who have notified us of their absence).
All members who have been kicked, if you are back once again, feel free to return.
