In my case, a while back I had some truly terrible luck. I had just deposited 0.5 btc in a 'quick registered' playt.in wallet, when my computer suddenly died on me. It just shut down without warning, due to a hardware failure (I later discovered that the heat sink died and it simply over-heated and shut down, at the worst moment ever). I had a pretty scientific method for using playt.in, because I noticed that I could never seem to find contact info for the admins, so I always tried to be careful because I knew if something like this happened I would be in this boat....
Playt.in has a quick registration where you just click a link and you have to save a unique URL in order to log in to your account. Typically, I would save the unique URL to my password database on my hard drive, and then also save a copy on a USB flash drive before sending the coins. But this particular time I got distracted for half a second immediately after sending the BTC, and forgot to click 'save' on my password manager program... I also was using the TOR browser at the time, so there was no history to retrieve my login URL with either... believe me, I searched... bad circumstances.
The Tor Browser Bundle must cache directly to RAM or something, because there was no trace of the TOR brower's history anywhere on my hard drive... I tried using data recovery & forensic software from a live Kali Linux disc, digging through the SQlite db's that tor does cache to disk during the current session, and everything else I could think of. Well, it turns out that the TOR browser does indeed do it's job well, because there was literally nothing to find. I posted a thread about it here:
https://bitcointalk.org/index.php?topic=822469.msg9191064#msg9191064 I have been trying to contact the admin ever since, as I can prove that I own the wallet that the funds were sent from. There is a link to the blockchain record of the transaction in that thread as well. The funds sat there for a few months, I could not get them, and then one day they were moved. I am assuming at this point I will never get them back. So sure, it is technically all my fault, as there was no fault on the server side ...however, I for one believe that if one is to run a site that deals with currency like playt.in does, then one must be reachable in case things go wrong, like they did in my case. That is why I say do not trust this site. No communication==You're screwed if something goes wrong (you know that old saying, 's*** happens'...)
I wonder if there is a chance to find the persons behind. I don't have a clue where to look, who to ask or hire and so on. Any idea?
Regarding your problem... i use a freeware named Ditto. It saves everything that was in clipboard. Of course one should set it up so that it doesn't store passwords copied from keepass. But its very helpful. Simply copying a link and it can't be lost anymore. It saved me often from data loss from pc crashs because it saves it instantly itself.
For internet forms like forum posts i use FF-Extension Lazarus. I didn't lose that much from not doing it before but it's annoying in any case.
