OF course, Wulfric didn't use his real name. No matter how annoyed he was by the posts and comments that he had read, there was still a bit of sense left in him. Using his real name in this kind of situation would lead to a lot of negative consequence.
There's Leland who would definitely nag at him if he mindlessly used his real name while replying to those comments and posts. Then, there was also his brother who would just make things more complicated. But most of all, it would be Aster who would receive the brunt of those negative consequences.
If it was just Wulfric, yes, he would not hesitate to use his real name to give a tongue lashing to these people. But no, if he did that, the only one who would be affected was Aster.
