Google is shit nowadays, sadly - it used to be you could Google "Tim Buckley Jackie" and see the picture yourself. A girl's name written on his junk near his pubes.

It got out on his forum and he banned anyone who mentioned it. He wound up doing a complete purge of the CAD forums and got rid of half his mod staff. It's not just a 4chan thing; it was all over the internet like... 15 years ago. (Maybe longer?)

I've had the unfortunate displeasure of having seen it one time, so I can vouch that it exists. I can't find it nowadays, but I can find people referencing it:

• https://imgur.io/gallery/64U1u

• https://www.reddit.com/r/HobbyDrama/comments/liy37w/webcomics_from_rise_to_loss_the_story_of/gn7abwq/

Etc.

If you do the search now you can see that Google removed some results "for legal reasons", which is likely the EU "right to be forgotten" law being used to scrub it. But it used to exist and was well-known for anyone who was on the internet in the long long ago times...
