I haven't had any of my blog links refused or deleted, and that includes the occasional link to my Tumblr blog. Links to a pay site are a total no-no of course, but otherwise I think you're OK.
Links to my story site are flagged as inactive, so they don't appear as a link. I have two sites, one commercial and one containing the free stories I publish on sites like SOL, so I doubt it's a commercial issue. However, like a lot of things, I doubt the restriction is universally applied. Instead, I suspect it's a case-by-case judgement call by each administrator who processes the post.

I'll give the moderator a note. Plan A will be to do the link. Plan B if needed will be to have the Notice direct readers to my SOL blog.
I was referring specifically blog posts, not within the context of the story itself. But I've seen it happen more than once, so I doubt it's a completely random fluke.
Bondi's solution makes sense, but since I've had active links inactived in the past, I simply don't submit them using display text anymore, instead listing the actual website (i.e. "www.crumblywriter.net" instead of "http://www.crumblywriter.net", rather than "My website").
