Spam

Nonsense text and promotional links are an ever-present problem on this wiki. Those who add the pages don't seem to understand that these wiki links don't add anything to their pagerank and are just a waste of their and our time.

Nevertheless, spam remains a problem and it seems that only one or two members on this wiki are allowed to delete pages and/or block users. Other wiki members spot the spam but can't do anything about it. They can blank the page, but then as soon as the page gets deleted, so does any record that the page was blanked. So in effect it's worthless for normal users to spend any effort fighting the spam, because their efforts will be deleted too.

Shields up again
I have added some new captchas and the spam burden seems the be heavily reduced. Let's monitor... Cheers Markus Neteler 00:33, 31 May 2012 (PDT)
