Dilemma of a blogger

Recently I read a post on FB's popular food group where the moderator had put a food blogger on a tricky spot.  He mentioned a blog post of her mentioning how bloggers these days do anything for free food and stuff. In addition, he commented on her style of writing and error in English. Being a moderator of such a popular group, the person gained support from many people who lambasted the blogger with comments ranging from her knowledge of English to her even considering herself worthy of becoming a blogger. Only a few spoke in support of the blogger. (Those people were in return indirectly asked to leave the group for going against the moderator.) Wonder if the girl in the context is even aware of this post. Firstly I wanted to share this with all my fellow bloggers as I felt bad for that girl. Secondly wanted to know your opinion on was it right on the moderator's part to do this kind of thing? How would you feel if you would have a similar experience?
