If no one from the Batley club read it. It means nothing.
Also how can anyone prove someone from the Batley club read it?
You have a point. I suppose it depends if someone from the club staff is a regular poster and posted on that thread.
What it does indicate is how desperate they were for players. There may be news articles from the rugby press and the local paper that indicate that too. It isn't in itself proof of anything but may demonstrate a reason why they felt the risk of playing an illeligible player worth it.
When you are gathering evidence, every little helps. Anyway the legal people will know if it's worth keeping
