First off, I'd just like to thank you for taking the time to report hackers and make the MCGamer Network a better community. While the staff team gets tons of abuse reports each day, we take the time to look through and discuss the evidence given to us. If someone is breaking any of the rules, they will get punished appropriately based on which rule(s) they broke and how many times they do it. We don't permanently ban someone for hacking the first time because we want to give players a second chance to prove that they won't do it again. Sure, someone might ignore their offense and go ahead and break the rules again, but others will understand this and learn from their mistakes. You suggested a perm ban for obvious hacks, but aren't all hacks obvious? Isn't that why we ban them? For hacking? You also mentioned that there should be a perm ban on second offense hacks and, this might surprise you, but you do get banned permanently for second offense hacking.
This is not true. We tell people to not delete evidence they uploaded because we need evidence incase we want to look over the footage at a later date when, for example, someone wants to see why they got banned or dispute their ban. If someone doesn't want to keep the evidence, why keep even upload it? We let you put it on unlisted so your channel isn't flooded with abuse reports.
