Mu kuyesa kwa chithunzi, mumasintha ziwalo zonse za fano zomwe ziri ndi chinthu china, monga chizindikiro cha msewu kapena galimoto. Yankhani molondola, ndipo mupitilize; Yankhani molakwika, ndipo mwawonetsedwa ndi ndondomeko ina ya chithunzi kuti muthetse.
Ogulitsa ena amapereka luso lamakono lomwe limachotsa mbali ya "test" gawo la CAPTCHA mwa kupereka kapena kukana webusaiti yokha pokhapokha pa zofunikira zina zokhudzana ndi chitsanzo cha kugwirizana kwa gawo la webusaiti.
Ngati pulogalamu ya chitetezo imakayikira kuti palibe munthu akuyendetsa gawolo, imakana mwakachetechete kugwirizana. Apo ayi, izo zimapereka mwayi ku tsamba lofunsidwa popanda mayeso oyimira pakati kapena mafunso.
