(Assuming you're talking about smp.opticraft.net as opposed to creative. Additionally, I can't find records of an account called Chuck_Knoblock. However, there is one for PJsnake)
MrParkourRaven was banned due to suspicion that he was an alternate account of yours. As you two share an IP address, its very hard to know if two players are separate, or its one guy with two accounts.
For this reason, I'll just handle both ban appeals at once, as it is unlikely that we will be unbanning one without the other due to ban evasion risks.
You've been banned many times for griefing, although only in small quantities.
I'd be willing to unban both accounts if you could apologise, and promise me that neither you, nor your brother, will grief again.
