Yes it is important to point it out. People used to show support with their money and word of mouth. Example, I will never buy another electronic device from SONY, due to a failure on the part of their customer support. I will recommend to people looking for an inexpensive good quality TV/Monitor VIZIO, mine is now 7 years old.

Do I rant and rave example:

I'm "unsafe". WELL I AM UNSAFE, MOTHERFUCKERS!
I'm unsafe to your asinine, bullshit "editorial staff"
unholy alliance you want to foster and maintain between San Francisco and Saudi Arabia.
I'm going to fuck up your idea of what your platform should be until you spineless, craven cunts ACTUALLY BAN ME.

Do those statements really serve to resolve the problem, to get the word out, to show that there is a problem? (Which there is), or does it show the mindset of an individual that is hurt and angered at being ignored?

Less colorful language could have been used and the message may have been better received.
