Real quick were yes i agree with the notion that racism shouldn't be a thing on the star wars site oocly. Icly it's still something that's more or less obvious in the setting. Secondly, your terms of service and privacy policy do not expand to discord services that are not directly owned by you or the site owners regardless of those who use the site as a social media, RP, and discussion area, more so neither your terms of service and privacy policy states explicitly that " if your Discord exists as a result of this community, I can and will easily claim jurisdiction. It would be extremely negligent for me not to. Context and circumstances will be considered, but as an internet community, there are no laws that bind how far our rules can extend beyond our own limitations."
Having said ruling would need to be explicitly stated in your site's privacy policy and terms of use on top of which you would need to classify as a business that makes money from your service in order to exercise that claim due to legality reasons. as like you said it's an internet-based community on the site therefore you would be infringing on the rights of others protected by the right to free speech and freedom to assemble.
now I do agree with you that these issues you're having within your community should not be happening but combating it with action that can get the site shut down due to breaking previously and basic rights laid out by internet laws isn't okay either. especially as your also guilty of breaking one of your own terms of service rules; paragraph 4 line one and two of your sites terms of service state "You agree to not use the Service to submit or link to any Content which is defamatory, abusive, hateful, threatening, spam or spam-like, likely to offend, contains adult or objectionable content" and on Oct 5, 2020, you had stated "If anyone else wants a ban to feel free to just send me a PM rather than blow up this section of the website which is reserved for cringe musical tastes, unsolicited opinions, and unprovoked surrendering of privacy. Also, something <3" which in of itself could be considered spam-like and likely to offend as well as the statement "Also, something something <3" could be misinterpreted as something not suitable for people under 18.
i thank you for taking the time to read this comment and I hope you have a blessed day and continue to do your best and making this site wholesome and appropriate for individuals 13 and older
