>They posted it for a reason. [...] Why would they even post the pic if not looking for the owner?

As they explained multiple times, they took a photo and posted it because they were in the area when a large snake was found in a place where large snakes are normally not found. People post things they think are interesting. That's all it appears to be.

>People post lost dogs and other pets here all the time and thats ok.

Yes, because most of the people posting those have actually caught the pet and are holding it as long as they can as they to locate the owner or find someone else who can take care of them.

There are also a lot of people who post pictures of lost pets and do not have possession of them at the time they post it or know where the pet is.

>I want my damn pet. What else am I supposed to fucking do

I get it. Losing a pet sucks and I am keenly aware of the heartache one goes through when it happens.

Since you deleted your old username, it's hard for anyone who might have your snake to contact you on that post. So, make another post with pictures of your snake and ask if anyone knows of someone who found and has a lost snake.

But, and I can not make this any more clear, do not contact and/or harass that individual you've already interacted with several times and who told you very clearly they do not have it, do not know the person who took it, and don't have their contact information. Don't ask others to try to contact them on your behalf or pressure them to answering even more questions. Just... leave them alone.
