It seems the "report" feature of amiga.org isn't well known, so here's a quick introduction on how to handle spam efficiently.
If you see a message that you suspect to be spam (or malicious in other way), rather than posting a reply to the thread or adding insulting messages to the profile (*) of this user, it is far more useful to report the message in question. This way the admins will get notified immediately without need for them to actually notice the messages by accident. Another benefit of not replying is that the spam will drop out of the main view quite fast if not replied to.
To report a message you need to be logged in. When logged in you can see a report button on each message:
Click on the button and then give a short explanation for the report. In obvious cases (just like in the above picture) just "spam" will be enough. Note that you need to wait 60 seconds to report another message.
(*) Any attempt to insult the spammer is futile anyway: The spammer is a bot. There's no human involvement at all.
