I am aware that this is a bit annoying- I run into it a lot too!
But its a necessary evil if we want to keep our server fast for everyone, since robots drain our bandwidth and processing power...
Don't forget that a registered user could also enable a download robot/script, so being registered does not guarantee this.
The only solution I see is increasing the limit a little, so the Captcha appears more rarely. But again, we have to change the limit every so often so we don't get 'smart' robots that can work around it.
im not a robot, but when i am searching for a particular sound, i like to download all available options to see if they fit with whatever project i may be working on. it would be great if you are logged in, you dont get the robot security page when downloading more then 20 sounds.
