What is this character: ⿲舌⿳十⿴囗⿱龹贝⿱一八乚?
It is a polysyllabic invented "character", part of the online language of Chinese netizens (网语). It is a graphical representation of what one could call a "modern idiom": 贵圈真乱, guì quān zhēn luàn, roughly meaning "Your social circle is a mess".

The phrase was popularised on BiliBili, although its roots apparently date back to the mid 2000s. Baidu has an entry on the term. The use of 贵 as a sarcastic honorific is very much in vogue in Chinese netspeak.

The "mess" referred to can cover all manner of 'disapproved' conduct, although the general tone is not necessarily vitriolic.
