Ironically, if it actually was a venomous snake the actual safe course of action would be to leave it alone. I recall hearing a statistic that most people who get bitten by snakes get bitten because they were trying to kill the snake.
The people who made those cave drawings definitely knew their animals. Most of them are highly unlikely to show up in modern people’s yards, however.
– my next door feed is still mostly full of introductions and (despite my changing the settings) miscellaneous notices of statewide or wider area things I already knew about; though changing the settings has at least I think gotten rid of the pictures of wildlife people found in their yards on the other side of the country. If I want to see those, I can find some via google. For the most part I glance at the title and hit delete on the notification. I rarely go to the site itself, because it’s so slow to load and so hard to work with.
Yup. Because generally, if you’re not trying to kill the snake (or at least doing something to make the snake think that you are), the snake has no reason to bite you. Humans are way outside the size range for prey for snakes in most of the world.
The “every snake is a copperhead” reminded me of another Nextdoor thread from years ago.
Someone posts a picture of a spider asking “What kind of spider is this? Is it dangerous?”
Several people post variations of “It looks like a brown recluse to me.”
I post that brown recluses are not endemic to California, so it’s highly unlikely it’s a brown recluse, along with a link to a cite. Most likely it’s just some harmless brown spider.
The majority or people ignore my post and continue claiming it’s probably a brown recluse.
You are also describing Facebook groups for IDing whatever. Filled with Dunning–Kruger nitwits confidently shouting wrong or vague or answers. For instance beachcombing and rock ID groups often get questions about black rocks with holes through them found on the US. They are pieces of jet that have been drilled through by burrowing clams. But as sure as the sun rises half a dozen people will jump in to say that it is a hag stone. “Hag stone” is a superstition-based nickname for a rock with a hole through it. They are confidently asserting that a rock with a hole through it is a rock with a hole through it, thinking that they have contributed sonething meaningful. Also, any rock with a “line all the way through it” is declared to be a “wishing stone”.
As for vague answers, you get critter IDs at the genus or family level. I remember for example a post of a large beetle with eyespots that immediately got several answers that it was a click beetle when there are thousands of species of click beetles and what was posted was distinctively an eyed elater. It is like showing a four-legged domestic mammal hoping for an answer like “French Poodle” and getting a dozen people identify it as “a dog”.
I was just on a birdwatching (sic) tour where the guide did this. Way unimpressive!
So why do clams burrow through jet?
Actually, we had a lady post a picture recently of a piece of china with a marking on the bottom, questioning “what is this?” Several wags chimed in immediately to let her know it was a bowl.
I wasn’t one of them, but I laughed.
They burrow through rock for protection. They burrow through jet specifically because it is soft, and it is there.
Thanks. I did not know that.
I find myself oddly drawn to experiencing this fountain of Idiocracy for myself.
Is it easy to cancel your membership or whatever and forevermore not be bothered by the site and its advertisers? Or is it a one way trap door into spam-hell?
Does one need a membership at all? Obviously I need to give them some address to orient them to which local content I want to see, but beyond that?
Enquiring Morbidly curious minds want to know. 
True! If you absolutely must convince a snake to move away from where it is, a squirt with a garden hose will make it skedaddle.
My guess is the snake sees the garden hose and thinks, “Shit, that’s a big-ass snake. Better get outta here.”
But sometimes the snake just hopes to go viral.
We have counted at least 3 snakes in our yard. We’re doing everything we can to keep them here.
Spouse 1: Honey, that’s the doorbell. I’m all messy; would you get it?
Spouse 2: Sure. Sigh. … [peeks through peephole] Oh, it’s those darn Jehovah’s Witnesses again.
Spouse 1: Sic the snakes on 'em.
Spouse 2: Gladly!
In the nextdoor thread I griped about, the OP positively identified his mystery bugs as Largus bug nymphs. Yet ninnies are still posting to say they are ladybugs. I give up.
What, posting at SDMB hasn’t learned ya that people don’t read the comments before they comment?
'Zactly.
Skim thread title, don’t even glance at OP body, don’t read the almost 200 posts, then drop your turd pearl of wisdom in the collective punchbowl then move on.
That’s the smart way to do social media! I get to spend so much more time displaying my wisdom and waste so little time reading other’s drivel.
People. They bug me.
I once posted about an item I was offering for free. Even after I posted that the item had been taken, people asked if it was available. And the post only had maybe half a dozen replies. I learned that once a post has been solved, completed or is no longer relevant, lock the thread or it will get replies forever.
