No, it's not the first one. There's that user who always follows the same cycle: he asks a question marginally related to programming, nobody answers, then some time later (a few days, I think) he answers his own question, which often involves using some commercial product. Sometimes he skips right to step 3 by answering someone else's question in the same fashion.
Sometimes all the first threads of each forum have a spam reply that may not even closely related to the question.
Is odd that these spam things occur mostly during weekends
