OP, people would probably take you a hell of a lot more seriously if you acted with maturity. Bringing up "your mom" jokes isn't going to bring any seriousness/validity to the claims you are making:

As for sharding, I'm assuming it's relevant to sharding of databases, just put into the context of cryptocurrency/blockchains (in terms of storage of data). If it's a legitimate discussion, while it may be somewhat spammy to create new threads to discuss, the OP of that thread is in the right provided the thread has some form of value.

If they make multiple threads to discuss the same sort of thing, then that's a different story.
