Hi. I have noticed lately that I've have been kicked of the server a lot. I haven't been swearing or posting websites. I just talk casually and I am kicked. I was just kicked from the server then because I wrote on a sign "Gorgeous Skin"...
I have had the same problem, but my best advice is to not add anything that is website-related. Such as full stops after many words, clumping words together, and saying anything with .net, .com and other URL-related endings. I have also noticed putting multiplie commas after words can trigger a kick. Hoping they will fix that. There's not much to do but avoid any advertisement-related chat. Hope this helped!
The console is very sensitive and it sometimes thinks that the things you say in chat are either related to advertising or swearing. If you do keep on getting kicked, just ignore it unless you know you did something wrong in order to get kicked.
Some very important aspects to remember are: Do not say TV with words in front of it (ex: Let's watch tv) as this could be interpreted as watch.tv, which could be a link. Foreign characters on signs like ( ͡° ͜ʖ ͡°) will probably result in a kick. Don't excessively use periods or commas. Be overall mindful when typing in chat or writing a sign.
