I'm not completely sure but this may be a case of defamation. In this case it would be libel since it is in the form of written words. Although Synki is not spreading false information about Beetle179, the use of the name "SandNigger179" and "Nigger179" hinders Beetl179's ability to stream. This affects him personally and could potentially harm his "business" (streaming). The use of the names "SandNigger" and "Nigger" would not create a case for this matter. However, the numbers "179" are included which is a mark of Beetle179 and tied with his name/brand which is on his stream. KSF cannot do anything about this but provide evidence in the event of a lawsuit if Beetle179 decides to sue Synki.
