You should submit this request through Special:Contact.

However, from what you related here it does not sound like something they would perform a checkuser on. Which is generally reserved for individuals being *extremely disruptive*/vandals, suspected of gaming the system (using one account to supportively vote another), or evading a block/ban.

Still, submit to S:C, include as much info and links to support your allegations.
