Those are questions you shouldn't be asking in someone's selling thread. That's rude and should be something you keep to pms if you really must but at the end of the day you shouldn't be pointing fingers at anyone or putting your nose into someone else's business.
Are you a Mod? No. Is this an appropriate place to ask? No. Now then, if you have these questions, they should be asked in a private setting, like a PM as shinkuzame said. Unless the Mods feel like saying anything about it, you should leave it alone. Now then, there is a new rule that states the following
Do not intentionally provoke or instigate a negative reaction out of another user. This is also known as trolling.
