 ::SammiB is probably mother/wife/sister/daughter (but hopefully not all at once). COI doesn't come into CSD at all. That's more the province of AfD and/or the talk page. I agree with MusikAnimal that speedy isn't really appropriate here - check the references and look at notability rather than significance. I've not looked into the article with more than a glance. If there are IMDb refs, that's a good way of checking reality and possible hoax - if the ref goes to someone else's page, start thinking hoax. IMDb doesn't count for notability, but it's a good jumping off point, and like Amazon, lack of presence on IMDb means more than presence does. Think about that... As to the blanking, I wouldn't worry. The case is open, and the tag will be replaced if proved. I rarely bother tagging user page - I can't usually find the template and the clerk or closing admin will see to all that anyway. If I've blocked per WP:DUCK and there's nothing contentious, I just stick one on the talk page with a link to the master or sock.
