Any code I make for clients is under a strict license unless specified otherwise. It's a straight forward license pretty much stating that they can't sell it or claim it as their own. I've had a few clients break that license but one stood out. I had made a piece of software that cost her over $2,500 due to the amount of hours that went into it. The transaction went along smoothly so there was nothing to be alarmed about. She came back for more work about 6 months later and I decided to do some checking up on her to see how her business was going. Immediately smack bang on the home page was my software being sold for $30/month. Needless to say I was outraged. She said there was no talk of a license which I responded with pulling out the contract that she signed where it explained that signing the contract meant she was in agreement with the specified license. 2 months after this started, I'm being awarded any profits made from said software along with her closing down the website. As much of a bitch as she was, it wasn't worth my time trying to get more out of her.

I once had a client that lived near by and I had setup a server in his office. One day he calls me begging for help because it keeps turning off... He put it in a sealed foam box to try to reduce it's noise. Temps were 80+ Celsius (176f) within 5 minutes of it booting.

Back when I first started freelancing I worked for a client who ran a game server hosting company. My job was to improve their system for updating game servers. This was one of my first clients and I didn't dare to question the fact that he was getting me to work on the production environment as they didn't have a development one setup. I came to regret that decision when out of no where during the first test, files just start deleting. I panicked as one would and tried to stop the webserver it was running on but oh no, he hasn't given me access to any of that. I thought well shit, I might as well see where I fucked up since it was midnight for him and I wasn't able to get a hold of him. I looked at every single line hundreds of times trying to see why it would have started deleting files. I found no cause. Exhausted, (This was 6am by this point) I pretty much passed out. I woke up around 5 hours later with my face on my keyboard (I know you've all done that) only to see a good 30 messages from the client screaming at me. It turns out that during that time every single client's game server had been deleted. Before responding and begging for forgiveness, I decided to take another crack at finding the root of the problem. It wasn't my fault. I had found the cause! It turns out a previous programmer had a script that would run "rm -rf" + (insert file name here) on the old server files, only he had fucked up the line and it would run "rm -rf /". I have never felt more relieved in my life. This script had been disabled by the original programmer but the client had set it to run again so that I could remake the system. Now, I was never told about this specific script as it was for a game they didn't host anymore.
I realise this is getting very long so I'll speed it up a bit.
He didn't want to take the blame and said I added the code and it was all my fault. He told me I could be on live chat support for 3 months at his company or pay $10,000. Out of all of this I had at least made sure to document what I was doing and backup every single file before I touched them which managed to save my ass when it came to him threatening legal action. I showed him my proof which resulted in him trying to guilt trip me to work for him for free as he had lost about 80% of his clients. By this point I had been abused constantly for 4 weeks by this son of a bitch. As I was underage he had said that if we went to court he'd take my parents house and make them live on the street. So how does one respond? A simple "Fuck off you cunt" and a block.

That was over 8 years ago and I haven't heard from him since.

If you've made it this far, congrats, you deserve a cookie!

I designed a logo for a family member's business with the expectation that I would receive payment once the work was completed. I wasn't expecting a lot, I only really do freelance work for software but I know my way around Illustrator. I'm not one to charge family anywhere near full price and I felt no contract was needed. We were back and fourth for a little bit, getting the logo to his liking. Silly me during all of this didn't watermark any of the images I was sending (didn't think I'd have to, you know... Family) and a little while later he's gone and ordered shirts with the logo on it without paying or even contacting me. When I confronted him about it, he pulls out the whole "No contract was made" bullshit. It's ridiculous how arrogant people can be, I was asking for $50. I put a good 15 hours into it with all the alterations he wanted. 15 hours I could have spent on actual clients.

TLDR; Designed a logo for a family member without a contract, he decided not to pay.

It happened! I found the answer I needed on page 4 of Google! Mind you it was among results such as "Watch Visual Studio S02E14 for FREE"

When will people understand that you can't get quality software made for $5 by some random from Fiverr? Just as I'm about to confirm a quick Freelance job they tell me they've found someone on Fiverr that will do it for a fraction of the amount. It's happening more and more. Don't get me wrong, I'm still getting plenty of work but I see it as a bit of an insult. Comparing the quality of work I do with someone who pumps out 5 programs an hour.

And yes, I do realise there are people on Fiverr that do care about their work, there just doesn't seem to be many of them.
