(1) I don't know how you define a formal submission website. Strictly speaking, except the magazine official website, everything else is irregular, but many magazines don't have official website, so you should know that from Baidu, official website is fake, and all of them are impersonators. Don't vote there, but if you want to vote, you should contribute through the HowNet system.

(2) There are submission websites, that is, paper publishing websites, but fake official website is not counted. Although fake official website is also a paper publishing website, they are not honest, so they are looking for a special paper publishing website, not a magazine official website's paper publishing website.

(3) For regular websites, many authors only know the industrial and commercial registration 400 telephone number, but it is not necessarily reliable. The most reliable thing is how long he has been engaged in this, whether the content of his website is original or not, and the professionalism of the service, all of which need your comprehensive consideration. I suggest you go to paper net, Tao Tao to see the anti-fraud knowledge in this field first, or you will be easily deceived and sent to fake journals. . You can ask if you don't understand. Good luck with your work.
