These are concerning public dhamma discourse and what is abusive circumstance
There Venerable Sāriputta addressed the mendicants:
“That is possible.”
When he said this, Venerable Udāyī said to him, “This is not possible,
Reverend Sāriputta, it cannot happen!”
But for a second … and a third time Sāriputta repeated his statement.
And for a third time, Udāyī said to him, “This is not possible,
Reverend Sāriputta, it cannot happen!”
Then Venerable Sāriputta thought, “Venerable Udāyī disagrees with me
three times, and not one mendicant agrees with me. Why don’t I go to
see the Buddha?”
Then Sāriputta went up to the Buddha, bowed, sat down to one side, and
said to the mendicants:
That is possible.”
When he said this, Udāyī said to him, “This is not possible, Reverend
Sāriputta, it cannot happen!”
But for a second … and a third time Sāriputta repeated his statement.
And for a third time, Udāyī said to him, “This is not possible,
Reverend Sāriputta, it cannot happen!”
Then Venerable Sāriputta thought, “Even in front of the Buddha
Venerable Udāyī disagrees with me three times, and not one mendicant
agrees with me. I’d better stay silent.” Then Sāriputta fell silent.
Then the Buddha said to Venerable Udāyī, “But Udāyī, do you believe in
a mind-made body?”
“For those gods, sir, who are formless, made of perception.”
“Udāyī, what has an incompetent fool like you got to say? How on earth
could you imagine you’ve got something worth saying!”
Then the Buddha said to Venerable Ānanda, “Ānanda! There’s a senior
mendicant being harassed, and you just watch it happening. Don’t you
have any compassion for a senior mendicant who is being harassed?”

Downvoting, pestering, contradicting and annoying the righteous is like that. It is wrong action.
"The practice of Dhamma, [1] the practice of continence, [2] mastery of this is said to be best if a person has gone forth from home to the homeless life. But if he is garrulous and, like a brute, delights in hurting others, his life is evil and his impurity increases.
"A quarrelsome bhikkhu shrouded by delusion, does not comprehend the Dhamma taught by the Awakened One when it is revealed. Annoying those practiced in meditation, being led by ignorance, he is not aware that his defiled path leads to Niraya-hell. Falling headlong, passing from womb to womb, from darkness to (greater) darkness, such a bhikkhu undergoes suffering hereafter for certain.
"As a cesspool filled over a number of years is difficult to clean, similarly, whoever is full of impurity is difficult to make pure. Whoever you know to be such, bhikkhus, bent on worldliness, having wrong desires, wrong thoughts, wrong behavior and resort, being completely united avoid him, sweep him out like dirt, remove him like rubbish. Winnow like chaff the non-recluses. Having ejected those of wrong desires, of wrong behavior and resort, be pure and mindful, dwelling with those who are pure. Being united and prudent you will make an end to suffering." https://www.accesstoinsight.org/ati/tipitaka/kn/snp/snp.2.06.irel.html
These are some of the harshest reprimands in the sutta.
