If this is indeed you, then nice to meet you.
I understand, and as I've said, spam is just the reality of operating an image board. Even captcha or other flooding measures are only so effective, so it is part of the game.
The only reason I made this write-up was the regrettable casualty of posts, and I just want to make sure everyone knows what lead up to it.
I'm sorry that this is something you've had to deal with from your userbase as the site has gone on. I really have next to no knowledge of your site's culture so I will avoid further comment and refrain from giving any suggestions as to how you might deal with it :)
I wish you the best, feel free to come around any time.
