Warning, there is at least one old thread -- "Deaf Kitten" -- which has suddenly been replied to, seemingly by valid replies BUT beware that there are strange links embedded within the replies tempting readers to click on them. If you check the identity of the posters, you will find they joined TDK only minutes earlier than the replies posted. This seems a new nasty form of spamming TDK.
So please be careful and DO NOT click on those links or any embedded into any other thread replies.
I've reported this to Kitten Master on the Deaf Kitten thread.
