I have blocked you for one month for repeatedly adding unconfirmed and speculative information, despite plenty of prior warnings from not only members of our staff, but also from other users. Please keep our rules in mind when using the site in the future.
As I have already asked you, stop adding unconfirmed information to articles. We have no idea if the Racing Headquarters will appear in Cars 3, and I don't know where you found out that Michael Wallis voices Dex Dinoco. If you do not start providing sources alongside your questionable information, you will be blocked.
When adding new or "obscure" information, you need to provide a source. For example, no official media claims Larry the Cable Guy voices Mator, so you'd need to provide a source to communicate where you got the information from.
Copying information word-for-word from other sites. While Wikipedia's licenses do allow any and all information to be hosted on Wikia, we as an independent community have decided not to allow that. Please take the time to just rewrite the information into your own words. Also, on the voice actor articles you did this on, we really don't need a lot of information about the people themselves. Please keep it to just their relation to the Cars series, and a short couple of sentences explaining what else they are known for.
