SUGO Chat Restricted: Request to Restore Message Sending Access

I am using the SUGO application and my account appears to be restricted. Since today, every time I try to send a message in the chat, my message appears in red with the mention “restreint” and it is not delivered to the other person. For example, when I simply wrote “Cc” and a greeting to someone, the message immediately turned red and could not be sent. I do not understand the reason for this restriction and I have not been informed of any violation or problem with my account. I kindly request that my account be checked and that this restriction be lifted so that I can respond normally in the chat again. My username on SUGO is as follows: [NOM D’UTILISATEUR]. I ask you to review my situation and restore my ability to send messages as soon as possible.
