I've noticed that, while some users are helpful and courteous, others are self-righteous, pompous, arrogant and, frankly, ignorant of any social graces.
How do I get rid of them?
How do you block a user? / How do I get rid of them?
Well, it would seem that there is no technical solution implemented to that end, see i.e. here, unless you want to resort to client side userscripts. If you need a feature to block users you will need to take this feature request to meta.stackexchange.com as this is an issue for the network not this particular site.
I think, however, that this is by design and that a personal block list would not benefit the site and the community as it circumvents the intended moderation of such problems. If you encounter content (questions, answers, comments) that violates the Code of Conduct you should flag that content for moderator action. The help-page outlines the process of reporting and actions of enforcement taken on the moderators discretion.
Note that Stackexchange is community moderated, that is all users contribute to the moderation of the site using votes, flags, review queues. Please do not forget that the elected community moderators do not curate all content, do not read every question, and do not review each and every comment posted on site. Therefore we rely on all of you flagging any issues to bring them to our attention.
Assuming you mean here rather than your own server then:
But trying to be helpful, I'll point you to this old link that basically says - you cannot do it. There is a script linked in the text here but I've not tried it.
Like you, it was one thing I miss.
It seems there is something going wrong on the site that reduces our reputation. This compliant is not the only one. Also another user apologize and suggest better to use the Raspberry Pi Forum:
I apologize for the lack of answers to your post. The Raspberry Pi forums are a bit more friendly than this site.
I suggest that our elected moderators should get together to analize what's wrong with the reputation, whether it is a problem at all, or if it is a general issue, or based on only some of the active members, with the objective to improve the reputation.
@JörgWMittag. I'm very sorry if I ruffled your feathers. Perhaps I touched a nerve. However, I suspect that the reason the post didn't get closed is because other users agree with me, as evidenced by the upvotes. I would point out that, a case in point would be your own comment. In normal conversation, when someone asks a question, it is considered polite to address the person who asked the question in your answer. Conversely, it is considered rude to ignore the person who asked the quesition and address the rest of the "room" to critisise the question. But maybe that's just in my neighbourhood. ;-) As proof of concept, if I irritate you, wouldn't it be nice if you could press a button and remove me from your world? It works very well for Facebook.
@tlfong01. Please don't misunderstand. I'm not worried about "funny comments". I try to nurture a strong, self-deprecating sense of humour. What I'm disappointed in is users coming to the forum asking for help and being treated with hostility.
@Ghanima. I feel it would be presumptious of me to expect my input would be valuable as I am a complete newcomer here. On teh other hand, if you feel it would be, I'd be happy to contribute, and would welcome your suggestions as to how to proceed. However, the fact that my question received upvotes seems to suggest a will amongst the people.
