Incriminating how, exactly? Like, legally incriminating? Or just something embarrassing like you like futa furry bukkake porn?
I would recommend googling the name and trip you had used at the time (to the exact character, if possible) to determine whether it shows up easily with that specific incriminating post, and
to determine if anything which could link it to your real name shows up.
If you're extra paranoid, you could also try searching site:pastebin.com "[name/trip]", or various other sites sometimes used for this purpose like Doxbin.
If such a search yields no meaningful results, you're probably safe from all but the most dedicated of script kiddies and black hat trolls, a demographic you realistically have only a miniscule chance of drawing the attention of unless you're hanging out with the wrong e-crowd. And maybe the NSA. But you're not safe from those groups no matter what you do, so it's not worth worrying too much about.
