As mentioned in a comment, many scriptures that condemn the act, are given in this article. But i am not using that article as my reference.
The Devi Bhagavata Purana condemns the act at many places, irrespective of whether a Vaishnava doing it or even a Shaiva.
Here are few such passages:
32-40. Hearing their piteous cries, Durvâsâ, the prince of the Risis,
asked with a grievous heart the Pitris, “Who are those crying?” The
Pitris replied :-- There is a city close to our place called
“Samyamanî Purî” of the King Yama where the sinners are punished. Yama
gives punishment to the sinners there. O Sinless One! In that city the
King Yama lives with his terrible black-coloured messengers, the
personifications of Kâla (the Destruction). For the punishment of the
sinners, eighty-six hells exist there. The place is being guarded
always by the horrible messengers of Yama. Out of those hells, the
hell named Kumbhîpâka is very big and that is the chief of the hells.
The ailings and torments of the sinners in the Kumbhîpâka hell cannot
be described in hundred years. O Muni! The S’iva-haters, the
Visnu-haters, the Devî-haters are made to fall to this Kunda. Those
who find fault with the Vedas, and blame the Sun, Ganes’a and
tyrannise the Brâhmanas fall down to this hell. Those who blame their
mothers, fathers, Gurus, elder brothers, the Smritis and Purânas and
those as well who take the Tapta Mudrâs (hot marks on their bodies) and Tapta S’ûlas (i.e., those who being S’aivas act as they like)
those who blame the religion (Dharma) go down to that hell.
Book11, Chapter15
91-100. Vyâsa said :-- Thus dismissing the Brâhmanas, Gautama Muni
thought that all these occurred as a result of Prârabdha Karma and he
became calm and quiet. For this reason, after S’rî Krisna Mahârâja
ascended to the Heavens, when the Kâlî age came, those cursed
Brâhmanas got out of the Kumbhîpâka hell and took their births in this
earth as Brâhmins, devoid of the three Sandhyâs, devoid of the
devotion to Gâyatrî, devoid of faith in the Vedas, advocating the
heretics’ opinion and unwilling to perform Agnihotra and other
religious sacrifices and duties and they were devoid of Svadhâ and
Svâhâ. They forgot entirely the Unmanifested Mûla Prakriti Bhagavatî.
Some of them began to mark on their bodies various heretical signs, e.g., Taptamûdrâ, etc.;
Book12, Chapter9
A Brâhmana going to a S’ûdra woman is recognised a Brisalipati (one
who has married an unmarried girl twelve years old in whom
menstruation has commenced). So much so that that Brâhmana is
considered an outcast and the vilest of the Chândâlas. The offerings
of Pindas by him are considered as faeces and water offered by him is
considered as urine. Nowhere whether in the Devaloka or in the
Pitriloka, his offered Pindas and water are accepted. Whatever
religious merits he has acquired by worshipping the Devas, and
practising austerities for Koti births, he loses all at once by the
greed of enjoying the S’ûdra woman. There is no doubt in this. A
Brâhmin, if he drinks wine, is considered as the husband of a Vrisalî,
eating faeces. And if he be a Vaisnava, a devotee of Visnu, his body
must be branded with the marks of a Taptamudrâ (hot seal); and if he
be a S’aiva, his body is to be branded with the Tapta S’ûla (hot
trident)
Book9, Chapter34
Those who do injury to others even by the blade of a Kus'a grass used
as a weapon, go to hell with their heads downwards and their feet
upwards. Those that follow their own sweet free will, that take up any
sort of dress (e. g. Bauddhas), those that follow the philosophical
doctrines called Pâs'upatas, and the other hermits and saints and
persons that take up other vows contrary to the religions of the
Vedas, for example, the Vaikhânasa followers, those who brand their
bodies by the hot Mudrâs, at the places of pilgrimages, e. g. Dvârkâ,
etc., they go to hell with their bodies scorched by red hot brands
(Tapta Mudrâs)
