Have you increased the size to 250 x 250 or did you reduce the size to 250 x 250? Just thinking, if you increased the size, a re-upload might be needed to avoid blurring.
@ggsalas to prevent confusion, go to Settings > BuddyPress > Settings -> Activity Settings and make sure that “Allow activity stream commenting on blog and forum posts” is unchecked. That way, if someone wants to read/comment, they either go to the forum topic or the blog post page.
