WWOOFING/workaway stories?

I WWOOF'd on the top of a mountain in Colorado. There was no farm there. It was a couple of conspiracy theorists who wanted us to build an outdoor pool for them. It was over two hours from the nearest small town and my friend and I didn't have a car, so we were stuck on the top of a mountain. After the pool was built, there was nothing to do so I spent several days reading all of Les Miserables, which was the only book on the mountain that wasn't about astrology or aliens (it was a really good book and I strongly recommend it). They also made us work at their janitorial job at a fracking plant elsewhere on the mountain, which was an interesting experience. On the third to last day I got a panic attack and, thankfully, they drove me down.

Read the reviews I guess!

Not me but a close contact. They had a great time doing this in Japan.

One memorable story involved being handed a cutting tool and being asked to trim weeds growing between stones that were part of terrace retaining walls. Some of the weeds to remove required climbing the wall.

Apparently elderly farm folk are exceptionally strong and fit.

WWOOF'd in Japan the past spring for just 5 days with my sister, we had a great time! The property was in a rural/suburban town and accessible by train. The work was lots of weeding and vegtable prep and some garden work, it wasn't intense or excessive. We often worked along with the farmer.
Family was the farmer, wife, grandparent, and 1 kid. They were wonderful people and we integrated well, granted we can speak some Japanese which helped. Wife cooked breakfast and dinner for us every day despite working another full time job.
Overall had a great experience, and lucky to wwoof there for our first time!

I spent a summer wwoofing at a couple of places of Sweden. My experiences were mixed, and like others here I recommend doing your homework before deciding on a place. Things to consider:

1. What kind of tasks will you be doing? Often there'll be a list of the kind of things needing doing on the website but it's worth asking as well. Make sure to ask about what they'll need doing at the time of year you're planning on going. There might be interesting things but they all happen in the spring and if you're going in late summer you might just be stuck with busy work (I spent more time than I expected cleaning windows which wasn't exactly new or exciting).

2. What does a typical day look like? At one place I was expected to start work at 7 in the morning and carry on until 5 in the evening, while at the other things were more relaxed and we would finish up around 3 and drive to a lake for a swim. See if you can find this stuff out before hand and you can hopefully go somewhere that matches your ideal work day more closely.

3. How big is the farm/ how many other wwoofers will be there with you? Look and see how many people they accept at one time. Personally, I think it's best to be at a place with one or two other wwoofers. It means you're not the only outsider and it gives you more people to talk to, especially if the place is remote. On the other hand, if you're one of ten or so people volunteering, it can feel a bit factory-like (and at that point they're probably making money from the farm and you start to feel more like unpaid labour).

4. How remote is the farm? You might want to be somewhere away from everything but it's still worth asking if you'll be able to leave under your own steam if you want/ need to. This is only really relevant if you're not driving yourself, but is there a town/ village within walking distance where you can buy some things? Or a bus route nearby?

I'm sure there are other things you can ask while you're at it, but the key is to not be afraid to ask some questions before you settle on a place. It can be a really good time, and I really enjoyed it and learned a lot. But there are obviously places which take advantage of volunteers/ don't clearly communicate about what volunteers will be expected to do.
