As an owner of a couple of companies, I get almost constant unsolicited spam, SMS, and calls.
I generally ignore most. Occasionally, if I feel confident it will be honored, I unsub.
I just feel that it is corrosive, professionally, to complain about/attack others in a professional fora.
For example, LinkedIn often has stuff posted that could be used as a powerful emetic. I just ignore it. I may take note of the author, for consideration in professional relationships, but I won't usually say anything about their posting.
There are a number of subreddits, dedicated to sneering at others; I am aware of ones dedicated to sneering at programmers (having been honored by their attention).
While these may be de rigueur, while in high school or early college, I believe that it's a bad idea to continue participating in these types of things, once we start earning a paycheck. Often, the people we slag, can end up in a position to do us favors, hire us, or fire us. Some corporations simply won't even consider us, if our name shows up in these places (I know that the one I worked for was obsessed with brand protection, and would not consider folks that they believed would not reflect well on their brand).
That also goes for posting attacks; no matter how "genteel," in places like this very forum. I generally avoid getting into pissing matches with folks, hereabouts.
As George Bernard Shaw said:
Never wrestle with pigs. You both get dirty and the pig likes it.
