I just noticed a blog that one of my posts has been posted on is now doing this, although other posts on that same blog appear to be fine, maybe it's because i always spin my posts and that is what causes the problem. I've opened a ticket and they said
"That post will get picked up by our checking code and you get recredited automatically. Your post then gets published again so you end up with the right number of working links." So hopefully this issue is resolved, (or a system is in place to resolve it) I will check that post again in a few days and follow up
best regards
