How do you view today's two points of questioning regarding 'Mr. Doctor'?

Have you all seen the recent revelations about @暴走的加密博士 by @艾叔 ?

The main points raised are the two core issues of why the name has been changed four times:

1. Stopping profit-taking after only a 1% gain and then boasting about it.

2. Selling accounts to studios to 'cut leeks'.

Mr. Doctor, can you explain these two points?
