Personally, I believe a chatting spam bot is fulfilled the following criteria:
1. Random post something to attract your attention or curiosity.
2. Simply ask your question with a general answer. (not specific regarding your question)
3. Cannot answer a simple question if its programming does not cover them. (in this case)
"For example, are you a spammer?"
Last few days, I feel very suspicious about an account which are constantly trying to chat with me. Since I got some free time, I had decided to figure out who was there. Guess what, another spammer was confirmed within 20 minutes. The content of this verification testing is showed below:
