Ban Appeal Alpha2002

Just now, at 7:10 EST time, I lost connection to the server. I was patrolling with a normal rocket suit. I try to join again and the PING is 2500 so i thought the server crash. It really did because 55 people become around 30 after i refresh. I try to join in when ping is around 30 and was told I was banned.
??? I know the rule very well and at that game i hardly have a chance to violate any. I did infantry, construct and act as what was told. Please tell me the reason so i know what to reflect on.
Please reply me ASAP, and I am very grateful for your reading
Sincerely,
Alpha

If it is because I am doing live on Douyu.com, and if it is against the rule, I am very regret about this. Please understand as I have seen a lot of people doing live of PR and I thought it is totally fine. Sorry again if that is the case.
