Facebook isn’t letting me post links most of the time. It does let me post them some of the time. I don’t have time to deal with this right now so I’m just going to wait it out and hope Facebook takes me off its naughty list on its own.
I’m pretty sure I don’t have malware. I’ve scanned my Mac twice using two separate products, and it comes up clean. Nor do I see any other clear indications that I’m infected. There has been some weird behavior — including one incident that might indicate a possible failed attack — but I don’t THINK this machine has malware. I’m pretty sure it doesn’t.
I think that what’s going on here is that I’ve been trying some automated tools for posting to Facebook and Facebook has interpreted that behavior as a possible infection, like how your credit card company will flag your account if you take a sudden trip out of town and try to use your card there.
