Just to reassure you, we have been dealing with this, and removing the posts. As there was quite a lot of threads, it has taken some time to remove them all, but please do continue to report any spam that you see.
These repeated "buy your fake documents " threads filling every single topic are an example, "ExD", and they are a "Denial of service" attack on Gransnet, smothering the real posts with spam. As GN "moderators" seem to be all self-isolating this Saturday, I am counter-attacking with calls to contact a Gransnet director direct and make them aware of what is going on. (You can tell I have nothing much to do this afternoon)
I have all mine acknowledged too, ( it's an automatic reply, I think) but they haven't come back and replied about what action they have taken, as they usually do.
