Use the notify button on the post you would like changed or deleted, apologise say the post was inappropriate and can it be removed please. This was naive and enthusiastic of you rather than deliberate. I have myself had a troll online, and trust me it isn't an experience you want or need. Plus I removed a double post and a mixed up one that way.
The omnipotentcadet or everpresentjob will remove it. Bless them, our posting Angel mods with super powers.
