Anyone else keep getting their comments deleted on Instagram? Did they make a recent change to their anti-bot algorithms?

I'm banned from Instagram for about a week, after very innocuous comments of mine have been mysteriously turning up deleted. The people running the pages say they haven't deleted any of my comments, it's Instagram itself deleting my comments. I think Instagram thinks I'm a bot.

Is this just me? Or did Instagram fuck something up very recently?
