Can you see your /alts list? Didn't think so. You have no idea what it's showing. No, it wouldn't be denied instantly because you're appealing it and they are trying to verify if you're telling the truth. A Manager absolutely does change things when it comes to a case like this because they can view information about the accounts that senior mods cannot. If your accounts are matching but you're adamant that it's not you, then that's not "simple stuff", that's something that requires a higher-up's verification. Are you under the assumption that senior mods can view things like IP addresses and account location history? News flash, they can't. That kind of stuff is NDA-only. Hence the need for a Manager.
If you politely asked once or twice for them to take a look, it would (while unnecessary) be taken much better. Instead, you're crying about how staff are useless and horrible and stupid and clearly have no idea what they're doing. Do you think that attitude will get you anywhere in life? You're acting like an entitled pr*ck (no idea why that word is censored lmao). Cool off, take a day or two away from the forums, and come back when you can think straight.
