If you
understand what it is you’re replacing, what you’re replacing it with, and how to use the replacement
then you, almost by definition, are an advanced user.
A beginner should avoid these things, once you are far enough along to understand why you might want to replace one of these things, and form your own opinion on it, then go right ahead. But you’re no longer a beginner at that point.
Brandshield sent a fraud report to the domain registrar. Unless they are also your hosting provider, a domain registrar has no control over individual pages, only over the domain as a whole. So this was the only action you could expect to be taken, if you expected the domain registrar to act, and you sent them a fraud report hoping they’d act. So claiming they only tried to take an individual page down is disingenuous at best, and more likely just an out and out lie.
