Fight spammers or disable BadRequestHttpException in yii2?

Question

Yii

We use yii2 in the project.
The situation is such that errors like BadRequestHttpException
$_POST = [
'_csrf' =>
'Ki-Bdlk_dSCn0FyL9-bGt90Kn_NZOvlmlb_lMM05kQVGHvhGE3MDGOS-CvGDha7UhWCyiTtqy1TQ2oRV9VTdNA==' 'One' => '
name_id' => ' 'One' 7_id ' ==' > 'barbaraker' 'phone' => 'oIgjBcgApkqbSYsS' ] ] Would it be better to disable this error or catch suspicious actions and put a captcha if, for example, the csrf validation did not pass the request? Or how would you decide?
