I would consider it if it became a widespread, spammy problem, but I don't think that many people are confusing Bitcoin with Bcash on this forum.
That stance is somewhat vague. As I've pointed out to you recently, there are some users who have been intentionally shilling Bcash with new threads in the
Bitcoin Discussion sub-forum. Such users should be permanently banned IMO.
If someone is fraudulently passing off Bcash as Bitcoin, the most appropriate response is probably to give that person negative trust.
I fully agree.
