airbnb has blocked our accounts

We are an apartments rental company with 5 buildings of apartments in property and management. We have several airbnb accounts (one for each building). The account details and bank details are the same for all the buildings. We reply to messages and change prices with the same computer located in our booking department. Unexpectedly, airbnb has blocked the accounts for “technical reasons”. Could help me explain what has happened? Thank you very much in advance.  Joaquim
