I saw a thread in which OgN was apparently doxed but as of when I saw it, the dox was removed. The thread in question appears to now have been removed. Is this about the same thread?
Yes.
If Vod received merit on a post in which OgN was doxed, this is an example of a flaw in the merit system.
No, unless you want to censor what opinions, statements or other people's actions are allowed to get merit.
