It seems that Amac keylogger also support Mac 10.5. see here.

Eight times. And now referencing an OS that is 3 major versions old.

Nine. Oddly, they don't do that very often here. Maybe once or twice a year - the locals are a fairly civil bunch.

And, this type of thread is a magnet for spammers, and "Emma" seems to fit that mold.

Maybe, but it's an interactive spammer on a very slow burn then.

It's a spammer alright. 4 posts, all in keylogger related threads. With dubious links to keyloggers in the sig.

I'd say cull!

What I see is the inclusion of a couple of links that just _happen_ to be related to the thread, and to commercial products.
There's "in your face" spammers - and then the gentle spammer, no-mention-of-the-links (no real purpose, they just "happened" to be in the signature, and "Emma" only posts in threads that have keylogger as the topic.

You do realize even these are automated? Heck I've even seen automated spam runs that first ask a rather innocuous (and even on-topic) question and three days later "somebody" else answers it with links to malware infested sites, thanking them for the question.

I don't care if they do it fast and hard or low and slow, a spammer is a spammer. Kill it with fire!
