To add to what Hecate said, blogs can be a mix of IC and OOC. We treat blog comments the same way we treat profile comments. The main difference being we don't moderate the comments for spam posts or OOC content (as long as it's not otherwise offensive). Excessive flaming, filter evasion, or harassment is still going to land you a warn, but a spam or OOC comment won't. Posters of blogs are free to choose between moderated comments and unmoderated comments, but the comment section is not monitored by moderators for off-topic posting.
