Hello,
Awesome that you're going to report rule breakers, you help us and the community a lot with that!
Answer on your first question, 'Do they see my reports?'. Yes, of course they see your reports, you really don't have to worry about that. Some Moderators handle Spanish reports, some Moderators handle English reports and some Moderators Handle Dutch reports. It depends on which language you set your report, but they'll see and handle your report. Don't worry about that one! :)
Answer on your second question, 'How long does it take before a Staff Member handles your report'. It depends on how many reports there're submitted per day. It could take 2 hours, it could take 1 day. It really depends. So the best thing you can do after you've submitted a report, is just wait until your report is handled.
I hope I have you some information and I hope that I gave answers on your questions. But, if you have any more questions, feel free to PM me
here.
