Thanks for letting me know, I was able to delete those accounts.
Not sure if I said it before, in addition to sending me and/or OlympianProduct the user profile, a good approach to combating these website spammers is to also send in feedback. Use the feedback tab on their profile page or send a link of their profile and any other details from this page
imgflip.com/feedback
Lately I'm not on as much as I used to be, so also letting others at Imgflip know via feedback will probably help get the spammers removed as soon as possible.
