When we talk about "ragging on" someone or something, it usually means to criticize, mock, or tease them in a harsh way. But if you want to vary your vocabulary a little, there are plenty of synonyms you can use instead. For instance, you could say someone is ribbing, taunting, needling, or goading someone else. Similarly, if you want to describe someone as being frequently criticized or belittled, you could use words like heckled, berated, censured, or flayed. There are many ways to express negative feedback or ridicule, so experiment with different words and phrasings.
