parental guide vandalism

I noticed this TV-MA certificate addition to this title page which is obviously vandalism: https://www.imdb.com/title/tt14650120/parentalguide

Checking other titles, it's clear someone is vandalising kids cartoons parental guide pages in several ways, staff should perform a clean-up for the vandal (not for just the examples provided below)

https://www.imdb.com/title/tt9304186/parentalguide (both certification and all other parental guide items and votes are vandalism)

https://www.imdb.com/title/tt12042710/parentalguide (all certifications are vandalism)

https://www.imdb.com/title/tt7575284/parentalguide (certification vandalism)

https://www.imdb.com/title/tt21805224/parentalguide (certification vandalism)
