There are a few reasons that this isn't a cause for concern to me.
First of all, the member you're talking about apparently doesn't have BC. Therefore he cannot engage in any transaction resulting in him gaining money through any of Roblox's systems.
Secondly, the HICOM member may be very capable, and there's a great amount of leniency if this is the case; blacklisting him could do more harm than good. Special treatment, I find, is often not a bad course of action. It should be avoided unless necessary, but blacklisting a HICOM member should be about equally rare.
Thirdly, it may or may not even be genuine. It's the internet, people troll and make silly jokes that can be misunderstood when taken out of context. You provided a small snippet of the conversation. It could be an inside joke, it could just be a message or joke that was ill-placed or difficult to understand. The point is there's too little that's known to make a big deal out of it.

Well said Woopi. Like I've said in another post, RB does not condone scamming or anything of the sort, however we're not going to ban/exile someone for simply saying "I scam" on a public discord.
