Can autotrading companies like Option Alpha or tradesteward copy any subscriber's bots?

Let's just say you build your own trading bots and very successful in these websites (Option Alpha, Tradestward etc). These owners most likely have monitoring capabilities and know which bots are best performing among their users. So my question is, can they just look up these bots, copy them and just trade themselves without asking the account owner?

It just crossed my mind that it would be super easy to do that. I am just curious before I put all my efforts building my own bots using my own strategy.
