Dear @drifter1:

I apologize for getting 2 comments by @steemstem-bot on your post. The reason it was caused (when looking at the log file written) is that it sent the comment and received a 500 error code so it tried to send it again however both comments must have been received by the nodes. It happens to relatively few people compared to all the comments made. The other problem is that the other failsafe, which checks the most recent block for a comment made by the account on that post, only checks 1 block so if the comment is put in 1 block later then my failsafe won't work. Again, my apologies.

Sincerely,

Kryzsec
