this other thread
The author of that thread shows some of the hallmarks of the bots which have plagued this site since May--but not all of them. This leads me to wonder if this is really an individual who has casually signed on here, or a new level of bot development. If it is a human, then none of my observations about bots which i am about to make apply. This member responds to Tsar more than 52 hours later, and responds to Margo just one minute shy of 48 hours later. That could be a very human thing--the member signs up, and either through e-mail notification or through dropping by to see what responses, if any, he or she has gotten, returns to answer the responses.
If, however, this is a new development in bots, then two things occur to me. One is that it would be a very ominous and dramatic increase in the sophistication of the bots is this is a bot, and it is now successfully programmed to answer responses to its threads.
On the other hand, the nickel may finally have dropped for the creator(s) of these bots, and he/she/they are now taking an active hand to camouflage the bots by making responses for them so as to allay the suspicions of members of the sites at which the bots are directed.
Don't ask me what the telltale marks of these bots are--i'm not going to publicly describe them because i don't want give the bot creator(s) any clues to how it is that they tip their hands.
