Of the several media platforms that have been disabled, only one was a gunboard. I think the common denominator was most likely political, but including talk of violence, hate speech, racism, insurrection discussions, etc... call it what you like. There are tons of gunboards probably hosted by the same companies on the same servers that are up and running, including ktog.
I haven't look at the AR15 site in years, but I do recall it having some fairly "radical" types with lots of trash talk, insults, and likely some younger, testosterone driven, loudmouth, keyboard commandos that were not particularly well moderated. Has it changed? I don`t know, but my guess, in the current political climate, would be that it has changed more in that direction, not less. Feel free to correct me if they are now a bunch of choir boys that got shut down just because they discuss firearms. I did a cursory search or two trying to find a verifiable reason for AR15's unceremonious dumping but I drew a blank. My best guess is less about technical gun talk and more about political trash talk, i.e. violence, etc.
On the subject of political discussions, in my 20 years at ktog, I have seen more than few threads get down and dirty quickly before a moderator noticed. Sometimes a member starts a thread with something specific in mind that may sort of skirt politics. They don`t have the experience or the intuition to foresee the direction that other posters will take the thread. When I delete or lock a thread, it may be party due to the current content and largely due to where I absolutely know it will go.
When I started at ktog, the no politics, religion, etc rules were in place, but they were not at all well enforced. Old guard members may remember when Ray owned this little forum and kept it on his server. He was essentially AWOL and yzguy (1bad69) was the only moderator. He spent his scant time here on technical gun stuff and rarely even looked at the Counter. It got so bad at one point that the forum was barely useable. That's when several members split off and started the Keltec Range, and the two forums were essentially at war. Eventually The KTR fell by the wayside.
Since those days this forum has grown by leaps and bounds with new boards added to accommodate new guns and others added for a variety of purposes. I brought on several moderators, most of whom eventually parted company or limit their time and effort here now. It is mostly me doing the bulk of the heavy lifting. The avoidance of non-essential arenas for arguing, religion, politics, etc has served us well. Especially these days, there are ample venues to stake your ground on those issues. We here at ktog are best served by focusing on Keltec products, and other subjects wherein we are bound together as a community. Some folks tend to paint with a broad brush and pigeonhole people quickly berating "libtards, socialists, atheists, religious nuts" whatever. If someone is genuinely interested in KetTec/ktog, that's what counts. I certainly appreciate everyone who respects this forum, all of the members, and the rules that keep it a nice place to hang out. We have always welcomed conservatives, liberals, middle-of-the-roaders, and people of any color, creed, or background, so long as they have an interest in firearms, especially KelTecs.
- but this is starting to play out looking like a seriously worrisome means of censorship/control. A sign of more things to come?
