I think you should really try to build your reputation before advertising. There are always problems between bookmakers and customers, it is precisely how you deal with them.
This site has been around in the gambling world for quite a long time. He is also quite high in the reviews, I don't know where based on that by the way. It is indeed better to get red of that red flag.
You are correct, N2 has been around a long time, but its pretty likely the owners/management is not the same.
Most of Support staff as well left- anyone who used to play on N2 3-4 years ago knows this
I would not depend on N2's reputation of old, this isnt the same book anymore
