No, it is not.

The original question from Karim was about acquiring some IPv4 space. We
can absolutely infer he wanted that space to be publically routable *today*.

The facts are that *today* :

1. 240/4 is not space that will provide expected internet connectivity
2. There are no plans or timelines in place that would change #1.

You stated to Karim that there was a way he could get IPs for free , and
implied if he reached out to you off list , you could help him make it
work. That was intentionally misleading, and frankly doesn't reflect very
well on you at all.
