Ad hominen is when you use an irrelavent insult in an argument. Not every criticism of a source is an ad hominem.
Edit: to clarify, i think there is a huge difference between saying something like: national post is known to lean right and not really like the liberals so we should verify they are fairly summarizing the liberal proposed law by actually reading the law in question (what parent did) vs for example, national post leans right therefore everything they say is bullshit and should be ignored (which would be an ad hominem)
No, it’s when you argue the truth based on dismissing the speaker. So if Carl is an idiot, and Carl says cats are real, it would be ad hominem to say cat’s aren’t real because Carl said so. (Dismissing an argument isn’t ad hominem per se. Neither is name calling. It’s concluding based on not liking the speaker.)
Is it still ad-hominem if you actually agree with Carl? Doesn't it make Carl's argument even stronger when you say "I'm always against Carl but this time he's right" which is the opposite of dismissing his idea, ad hominem or not?
If you conclude X is right because Carl said so, it’s argument from authority.

No. It makes his rhetoric (essentially an argument about an argument) stronger. But not argument per se.
adjective - (of an argument or reaction) directed against a person rather than the position they are maintaining.
And they were given the benefit of a doubt and vindicated (in the commenter’s own opinion).
Meaning their position was judged on its own merits.
So not really ad hominem.
Ad hominem is a much more specific kind of non-rational argument.
All other arguments, directed at the source of the argument, that don't address the argument itself, are ad hominems.
Their expectation even had a reasonable explanation: their previous encounters with the source (as they saw them).
Then their actual judgment was on the merits.
And even their credibility expectations were based on actual experience (as they interpreted those) with the target, not something irrelevant to credibility.
It is a good example of someone whose experiences might have prompted them to make an ad hominem attack, but who didn't. The opposite of making such an attack if there is one.
Kudos that OP actually read it, but that doesn’t change “I thought the argument was weak because of who made it”
Bust most real-world news stories and other interesting claims of material fact (and even moreso, claims of things being good or bad) are not syllogisms where the major and minor premise are trivially verifiable and the conclusion either follows of logical necessity or not, but are, to the extent they can be framed as arguments, inductive arguments.
You are also wrong about what ad hominem is (there are plenty of counterarguments to a logical argument that are neither on point not ad honinem), but the bigger issue is that the subject here is mot a logical argument in th sense that would make your claim correct insofar as rejecting all counterarguments that do not falsify the argument by logical necessity.
"This source has a history of bias, but this article is accurate" is the opposite; it tells the reader not to draw an ad hominem conclusion.
