Error message when joining

[Julian Meyer]

When trying to join with core.disableIntegrityChecks(true); core.connect("ws://127.0.0.1:8090");

I get this in the logs
[NONE ][16:50:51] CONNECTED 127.0.0.1:52497, origin: "https://agar.io"
[NONE ][16:51:02] DISCONNECTED 127.0.0.1:52497, code: 1009, reason: "Spam", name: ""

Also this shows up in the console of the browser:

I recommend you use a client such as Cigar as the official agar.io client is unsupported.

As for the error you're experiencing i can only guess that you entered this into the console once the page has been loaded. As a result of this the core.disableIntegrityChecks(false) isn't registered. This makes the client send an integrity check to the server and as this message is too large, the server recognises it as spam and kicks the client.
