I asked my kid to look at the GBCA website/forum, with the question, what's going on. His reply was it coming out of Russia, that it was a bot dumping on the site, but didn't try to find the location. He has seen it on other open sites. He said someone should be able to put in a patch/block to prevent that much take over of the website.
Someone should be able to do that, but it is not me
