That's why I know this is caused by a hacker who has access to this site. I am apparently the only one not able to "reply" to any post.
UNLESS -- I am on a different device at a different location. I have already tested this out a few times since this started. You know from your end which public location I post from. So does the hacker. He has been able to block my replies from this location.
First - you see that other posters can reply to posts.
What happens for me is that if -- from this my regular posting location -- if I type a "reply", and then go to save it, the only button available is "preview". Makes no difference if I click this button once and wait several minutes, or click it several times. IT DOES NOT WORK. Up to today, after a while, an official looking message would finally appear, saying "site temporarily unavailable" and then I would be booted out of swampbubbles altogether. I knew it was hacking, as I could see everybody else could do "replies".
Then I discovered that hacker-boy hadn't been able to block me from original posts. So that is what I will now use to do any replies I want to post (until or if this can be fixed). I skip "preview" altogether on original posts now, and go directly to "save", and I am, so far, able to do original posts.
I've been doing this for 14 years, and have seen most variations that a hacker and/or troll will try. When J. Farah's WorldNetDaily was relatively new, and back then when most posting boards did not have the safeguards and protections they do now.... one hacker at that site was above to read posts as they were being typed, and actually had the ability to stop any typing mid-sentence. That didn't last long, because there was an easy way to circumvent that. But these guys are ingenious. This "reply block" is specific to me. Other posters are not having this problem, apparently.
One other significant note. Just now I tried to reply to a couple posts, including your "is it fixed?" post -- from my usual posting location -- but on a different device. Couldn't do it. Which means the hacker is able to block me at this location. But not others (I tested this out recently one time).
(This, by the way, is why I don't do any public message board posting on my computer at home -- hackers can way too easily identify one's IP address, and then proceed to cause all kinds of damage.)
