Something similar happened to me with Gads.
What I did was :
New domain/Hosting (I even used different payment method idk why).
2) New IP obviously and new user PC inside my laptop.
3) New IBAN for the CC I used to pay Gads.
4) I have changed all the description DRASTICALLY, changing few words didn't help unfortunately.
5) I have changed the campaign keywords at first, title, after few days I did as before.
6) I started with extremely low budget for the start and slowly increased.
These methods helped me after having the exact same issue as your experiencing and burned many accounts during the way. Let me know if you got any questions.
