Not sure what forum software is being used here, but…
In many or most forum softwares there is an ignore list feature which each user manages to their own taste. If you don’t wish to be distracted by the posts of User X you add them to your ignore list and then never see any of their posts in your viewing of the forum. Sometimes the blocked user’s posts are just collapsed and a particular post can be opened with a click.
Given that this feature is not available on this forum, here’s another method. When a particular poster annoys you to a sufficient degree you’ll remember their name and can thus ignore threads they start, and scroll by them in other threads.
Another solution which the mods could implement is to create a section specifically for new comers to SketchUp. New users could even be limited to this section until they prove their worthiness, however the mods define that.
Another solution is that each member can take responsibility for their own emotional experience of the forum, and the Net more generally. It’s not that rational to focus on the jerks (however that is defined) because there is an unlimited supply of them extending out over the horizon. A wiser more efficient strategy is to focus our attention instead on the one brain we actually have some control over, ours. This whole paragraph is of course quite unpopular because judging others is one of the more popular games on the Internuts.
Another unpopular strategy would be to remove screen names from posts. Given the human condition, what happens is that we become emotionally attached to our anonymous screen names and then have an emotional reaction when someone is perceived to have disrespected that fantasy identity. The content of a post is what matters, who cares that Snoopydog27 wrote it?
Little of the above is likely to happen here or elsewhere because we are creatures of habit and usually prefer to plod along in the rut of the status quo. We like what we already know, the familiar, the routine.
Forums are full of human beings. Human beings are routinely annoying. That’s life. Get over it, and get back to work.
