Persistent Instagram Direct Message Block

I keep getting blocked from sending messages on Instagram no matter what I do. This is really starting to get on my nerves. This has got to be the fifth time, and I'm really frustrated with this situation. I still get blocked even though I haven't used it at all. If this problem isn't fixed soon, I'll need to close my account. I've been banned twice for 48 hours, once for 3 days, and now I'm looking at a 7-day ban in a row, all without me doing anything wrong. I'm having restrictions placed on my account for sending direct messages. Could you please help me resolve the issue of not being able to send messages at the moment?
