Unfortunately, it's not that simple; there are competing considerations from the rest of the users here that I have to honor as well.

If I'm going to comment in a discussion, I need to place my comments in the most relevant place. I did not see, and still don't see, why I should inconvenience everyone else here by putting my comments in irrelevant, hard-to-find places, just to stick to the rule of not replying directly to Alicorn.

Now, take a look at the comment I actually made. Is that a harassing remark? Even if it's going back on what I said, it doesn't look like harassment. Now, if I had made a point of deliberately replying to every single Alicorn comment, then I can see it be harassment. But that's not what happened. And to demand that I not comment at all would just be bullying.

What's more, when people were (severely) modding her down for her rather rude "Leave me the fuck alone", I asked them to stop and explained the context.

I've made every effort not to respond to offenses in kind, but as always, "no good deed goes unpunished".

Incidentally, I had withdrawn permission from Alicorn to post on my top-level posts, yet I don't see similar censure.

Yes, it's an obviously ridiculous demand based on an oversized sense of entitlement and an extremely fragile ego, and Alicorn could not have reasonably inferred her comments were inappropriate ... but when did that ever matter?

and he agreed.

Yes, that was foolish of him and were I to have made an impulsive concession like that I would retract it before replying. But then I would continue to reply impersonally to Alicorn's comments as though they were from any other poster, refuting those that I disagreed with or adding related insights as appropriate. (I would hopefully not make dumbass comments like "where is Alicorn when you need her?")

The fact that he agreed just makes him a hypocrite when he breaks the agreement. If he hadn't agreed, that wouldn't make it appropriate for him to continue to bother me.

And: "Example: Talking to someone excessively without permission and continuing the conversation."

'Talking to' is an entirely different thing to replying to comments that happen to be made by you. If people are making statements here that others disagree with then those others should be free to make that disagreement.

Whether online or off, engaging personally is different to contributing to a group discourse.

Do you think I am attempting to damage someone's reputation

Absolutely, and very effectively. Silas's naivety when it comes to this kind of game helped. Apart from being somewhat disagreement prone, he tried to be conciliatory when you were going for the kill and was reckless when he was vulnerable to attack and needed to be impeccable.

For what it is worth I think you are being completely sincere in considering yourself a victim here. But I am less appreciative of sincerity than I once was.
