He is posting on Twitter and it is certainly helpful for traders learning to trade.....I found him a genuine and knowledgeable person.....what he does on Twitter is beyond our jurisdiction....we take what is useful to us .

I created a Twitter account just to follow him and have been tracking him from the Zerodha interview time. Unlike many who share bookish knowledge he is genuinely sharing his personal experience as I could relate to it from my own experience.
If a trader is struggling to scale up or trading consistently..he will definitely benefit by just following the daily trading logs he is sharing on his blogs. These trading logs can help others by giving them an almost real trading experience of how the trading account behaves over a period of time. This experience will build and train the mindset which is essential to trade successfully.
However one parameter that i think need to be tracked is the max drawdown. Growing the account aggressively as he is doing is not easy, the psychology plays a very major role. He is able to do this confidently means he has handled much bigger account size so even if a 50% drawdown for a smaller account size is not an issue for him. But for new traders it will be very difficult to handle. But once you gain the experience and confidence of trading a bigger size, smaller account sizes are child's play.
But even for experienced traders there is always a uncle point after which it's difficult to scale up. I cannot comment on his reasons for trading calls/ workshops but most successful full time traders go for it as trading like any business can have periods of drawdowns and does not give regular monthly income...by taking up other activities on the sides one can generate regular parallel streams of income. If one is giving genuine training with realistic expectations then i think it should be fine.
