#1 While I like it, I had to make the volume louder. For example if you listen to this video
https://www.youtube.com/watch?v=N6IxbRn8txY and then without changing the volume then you watch this other video
https://www.youtube.com/watch?v=hBBebIigmOk is louder.
b) I do not know, maybe know you were a bit sick and somehow it changed your voice (as I also noted you were clearing your throat time to time).
#2 Unknown for sure, bit it seems like you used a public Server. Why did you use a pubic server? Why not run you own server and not forward the port(s), so you do not have to worry about others joining and you have to tell them some thing like:
Alone. I am recording a video.

Note when I said
and not forward the port(s)
That is important because if you forward the port(s), then the server is a public access-able private server (not listed). Trust me I know, I been there - done that.
Depending on what software firewall you have on your computer, you may also tell the software firewall to only allow certain IP Address(es) to connect because as far as I know BZFS can only ban IP Address(es).
For example of what I mean by
only allow certain IP Address(es) to connect, I give a you single example.
Go to Start -> Windows Control Panel -> System and Security -> Windows Firewall -> Advanced -> Inbound Rule. Select the rule that you want to change. Then click on
Scope. For
Remote IP address, select
These IP addresses and then go from there...
