AntiLinkSpamPolicy forbids local user to post a link/attachment
it seems the policy is too aggressive and if a local user posts a picture in their first post, it gets eaten by the policy and shows error in FE.
see thread for context.
rin's theory:
AntiLinkSpam policy rejects every post with a link from a user that doesn't have local followers and posts and attachment links are not an exception
