From a letter published in Nature Magazine 15 October 2009.
http://www.nature.com/nature/journal...ture08472.html Introduction to letter; Cooperative social systems are susceptible to cheating by individuals that reap the benefits of cooperation without incurring the costs. There are various theoretical mechanisms for the repression of cheating and many have been tested experimentally. One possibility that has not been tested rigorously is the evolution of mutations that confer resistance to cheating. Here we show that the presence of a cheater in a population of randomly mutated social amoebae can select for cheater-resistance. Furthermore, we show that this cheater-resistance can be a noble strategy because the resister strain does not necessarily exploit other strains. Thus, the evolution of resisters may be instrumental in preserving cooperative behaviour in the face of cheating. Anupama Khare1, Lorenzo A. Santorelli1,2, Joan E. Strassmann2, David C.

I suspect it's yet another vague accusation of the mods being out to get him after his outburst against Moose.

Incidentally, I note that the system described in the letter does have a fairly close analogy to the BAUTforum, as the ATM'ers and CT'ers reap the benefit of the site without working to promote its main purpose.
In this analogy, moderators are the cheater-resistant strain.

Well, if you put one of those on it gives away the whole joke. I figured that if I was so presumptuous as to speak for the entire membership of this forum that the humorous intent would be self-evident.

Just incidentally, it has been shown that among populations of reef-dwelling service providers to larger predators (de-lousing, teeth-cleaning etc) up to 25% can be 'cheaters', i.e. just hitching a ride, before the system crashes and big fish revert to simply eating little fish. Apropos nothing much, it seems, in this thread lol.

Would somebody like to define a "cheating" and a social amoebae? Both of those attributes are odd to me when used to discribe them.
