Laravel Model recursion supress infinite loop

Having the following Laravel recursion in my model how do I avoid accidentally registered relation. What I mean: I have users and users can have many reportees and we want to get back the tree on a given user with the following snippet, which is works fine till the point if user is not a reportee to itself

/**
 * User can have many Reporters
 *
 * @return \Illuminate\Database\Eloquent\Relations\BelongsToMany
 */
public function hasreporters()
{
    return $this->belongsToMany('App\User', 'reporting_to', 'acc_receiving_from_id', 'acc_reporting_to_id')
        ->where('status', 'A');
}

/**
 * @return $this
 */
public function children()
{
    return $this->hasreporters()->with(['children']);
}

where can I check in the loop if a given id is not equal to the parent id
