If it was your pic, and it was posted by you….and then requested by you to be removed…and you didn’t retain a copy, then that is on you.
If you had in fact requested that a shared pic gets taken down, then why all this time later would you draw attention to it by mentioning a month/year of a competition while also sharing details?! If you wanted a pic to be taken down you would naturally hope offline copies aren’t retained out of risk of it being reposted anywhere…..but here you are asking that it be reposted.
I’m sorry but…..I call shenanigans on this one
