To the bro above, in no way I'm affiliated with TS, but on a neutral pov, throughout the 600+++ pages he has contributed to VN, I think he is very legit person irregardless of what.
Paying a fee or expenses you might call it is worth it better than you bang head bang wall to find out something you might never find out eventually..so I see totally not a big issue at all .
Nothing comes for free, see doctor also must pay consultation fee without medication tio bo..money is superficial, experience is more important. A few dollars to gain knowledge and experience.....mai niao lah ~~
