This happened two or three weeks ago and it's happening again. Spammers are using Nabble to attack R-Help. The psts are signed radhi and the posts' titles are taken from previous posts and therefore seem authentic but all messages end with "click here". I suggest you don't. And don't rply to this "radhi" And again on a weekend. Rui Barradas

If either of them contains the string "nabble.com", then the message was either posted from Nabble or is a reply to a message that was posted from Nabble. Delete both types, and Nabble ceases to be a problem. Duncan Murdoch
Can the Statisticians here develop some good Statistical tool to stop this Spamming keeping Type-I error almost zero?

In the terminology of Hurlbert (1984), a classic in ecological statistics, this is the difference between "non-demonic" and "demonic" interventions; the tools of statistics are generally intended to guard against non-demonic intervention only.
