Have you ever accidentally necroposted?

No but I am guilty of replying to threads that have been necroed by other members without realizing they're old threads.

Technically no, but like @Sharonia I’ve been the second or third to post after a necro, not realizing the thread had been necro’d.

I too have posted in a necro'd thread without realizing it was necro'd.

Yes but only when it has already been necroed.

what's next? A poll about whether (and if so) how many times you've polled? :(

Haha, I just love polls. :p

Nope.

I've only done it once on purpose, but I was the one who originally started the topic. I did it because I had found some new information pertaining to the subject. I added the information for those who do a Google search on the subject.

Now I have been guilty of commenting on a post that has been necroposted, only because I didn't realize that they had been until after I added a remark. Now I try very hard to look at the original date of the post to make sure I don't anymore.

Yes but only after someone else did, as I read this forum by "recent discussions".

I won't be the first one to resurrect it but sometimes I chime in then have a smack my forehead moment that the thread died years ago. Now and then though I have no shame if the subject is interesting and someone other than me resurrects it.
