I meant my comment to read like this:

[My opinion on trusting DDG] - [Reason for my opinion on trusting DDG].[More information about the reason]

In this case, because I don't use the "personal attack" to reach my conclusion that the person was wrong, I don't think it would be a case of argument ad hominem.

But if someone read it like this:

[One reason for my opinion on trusting DDG] - [Another reason for my opinion on trusting DDG].[More information about the second reason]

Then I am using the "personal attack" to reach my conclusion that the person was wrong, so I think it would be a case of argument ad hominem.

My comment wasn't written very well, and I'll try to write better comments in the future. Not that adding an ad hominem to a valid argument makes it invalid, I guess?. But it's still good to avoid fallacies, and to write one's comments so they're likely to be understood the way one meant them.
