I can’t say for sure that this is Bitseven, but so far I have been trading with them and everything is very similar. I may be wrong, time will tell. As long as I like everything, there are no problems.
As I said before, that's a weak reasoning. Take a look at kucoin and binance for example. Although they are very similar, they are not the same company/exchange.
But I do I agree that there are/there won't be any problems for you because you are affiliated with the website which explains your unconditional love for it.
