Having no bots and newbie items being expensive and hard to find is incentive for new players to join. A bot infested server we've experienced before many times, let's try one without then discuss.
New Players will level fast enough to stop farming those items though and the demand is way higher than a new player temporarirly might farm. And high level players won't farm these items. People'll rather just alt tab to some CS:GO/LoL.
