From what everyone has said here, Tweets to @airbnb seem to work best, but you need to be more clear on your first post there than you were here.
I suggest that your Twitter post say
"All of my listings were suspended without notice or AirBnB hearing my side! After a guest at one unit in Houston complained about the internet not working following the Texas power outages, I went to the unit at the guest’s request to fix the router. When I entered the unit was full of marijuana smoke and the windows were wide open during still freezing weather! I reported this to AirBnB, but apparently the guests told AirBnB they felt “unsafe” because I entered AT THEIR REQUEST!
They were the ones violating Texas laws by smoking an illegal substance in MY house! Why is AirBnB suspending my listings? I’m not the one that broke the law! AirBnB, I’m requesting immediate reinstatement on Twitter because you will not communicate with me. If you do not, I will continue to repeat this account of my experience on social media."
This is based on my assumption that they complained internet was out. If that wasn’t the case, yes, if you entered without warning you may have a problem, but I still think that it’s AirBnB’s fault for suspending you with no notice and without listening to your side. This happens far too much and it’s partly because the contract phone answerers are no longer properly trained, the turnover is too high.
I would also post to AirBnB’s accounts on Facebook. I don’t do Instagram, but if I did I would post there too. Apparently they do respond.
