These tip will help you to create and operate a bot farm.

• First of all. If you don't use bot farm and don't mask IP then play with your bot manually! Anything you do besides botting on regular basis will hide your bot. Miner is safest bot for you. CCP has hard times to distribute where is miner-bot and where is a human. A lot of humans afk mine, false positive chance to detect bots using statistical approach is so high, that CCP did not ban miners for years now. Only greedy miners who run bot 16+h/day and miners linked with mission based bots (abyss bot, faction warfare bot) are found. Since CCP introduced relist fee and removed margin trade, trade bots went to shadows too. There were no ban waves of traders since trading changes. CCP do not ban couriers since they removed 4th level missions from alfa accounts.
• Bots used for RMT bot farms with new alfa clones (abyss hunter and faction warfare bots) are checked by CCP on regular basis. Playing manually and use bot not every day is obligatory. Or be like a farmer, create new account under VM with IP masking to replace account in case of a ban.
• If you don't play manually with your bot, mimic human. Open activity tracker. Level one or another rank manually. Install manufacturing or research jobs, kill NPCs and salvage wrecks sometimes, do planet interaction jobs, visit systems you never visited before etc. If your activity does not level any rank in activity tracker (like sending mails or chat in local) it is useless.
• Don't run bot longer then 12h/day per machine. Attempts to start several bots from the same machine at different time will not work. CCP will accumulate worktime from machine and flag machine and all accounts started from it. Use virtual machine to properly separate your bots. Use vmmanager to start and stop virtual machines one after another and save machine resources.
• Brand new alfa clone may be flagged if you start it for longer then 5h/day. Reduce bot time during first two weeks. If you did not use old account for a long time, also dont start it for 12h/day from the first day.
• Create new accounts in advance. Never create two accounts on the same day. Minimal delay is 3 days, a week is recommended. 
• Use proxifier to mask your IP address. Check parameter 'route' using ipinfo.io If 'route' is the same for two machines then machines are linked and only one of those IPs may be used. In menu->tools activate IP guard and add negative mask: -xxx.yyy where xxx.yyy is part of your real IP. Bot will not start eve if you real IP compromised.
• Don't link your accounts ingame. If you want to transfer ISKs better to transfer character with ISKs or skills to new account or transfer ISKs via market: install sell order for 200% of Jita price, wait a week, buy with bot. Don't create accounts using referral link. Don't gift PLEXs from one bot to another. If you want to link accounts and transfer ISKs, do this directly. No need to jettison anything to space. The more suspisious transfer you make the more attention from CCP you will get.
• Create new account inside virtual machine when it is ready. Never login outside virtual machine with this account. You may not login to game and to any websites using API from your host computer. If in doubt open your personal area inside virtual machine and check login history. If you see your real IP address in login history you made something wrong and better to recreate account! Use firefox to browse internet under vm.
• Solo bots are not so interesting to CCP, they are looking for bot farms. You may have several accounts flagged but not banned for years. If you have several flagged and linked accounts, they will check you on the next ban wave.
• Alfa accounts are checked 3x times more frequently then omega accounts. Don't run abyss hunter, courier or faction warfare bots with alfa account for longer then one month. They are making missions and it is not difficult for CCP to understand that operator of those accounts is a bot as no human do thousands of the same missions every month.
• If you want to add ISKs to our bot to start trading don't purchase ISKs from dealers. Better to purchase character with skills, do character transfer and monetize skills with extractor. Also it is better to purchase PLEXs from CCP, why not? Trader will double your funds in 2-3 months. Connection to ISK dealer account will stay forever. Trader may generate you income for years, one month delay in the beginning is not so bad for the sake of safety!
