All cases of bragging about having an exploit and not sharing it will result in infractions and / or bans. If you want to share something - share it, but if you don't want to share it - don't make any thread's / posts about it.
If you want to sell exploit on OC, you need to "send a copy"of said exploit to OwnedCore Administration and ask for confirmation of it's legitimacy - then you can sell it in Trade Section, and Trade Section only.
