Land Rover Series I, II, III Club - Forum

Iin the Introduction section, there are several posts in a foreign language. I've posted asking for them to be translated but nothing.
How does this happen and what's being done about it?

Those are spam messages and should be deleted and the account suspended.

TBH, I think the number of spams which remain visible for a long time do not give a good impression on the forum, sadly.

I've reported them and there's been no response.
What is being done about them? It seems the forum administrators are somewhat lax.
