At least, I have a script that runs every minute, and if the clipboard contents has not changed, it flushes it. This really helps in preventing accidental paste of sensitive stuff that remained in the clipboard.

I also have script that strips newlines (so I can relatively safely paste into terminal without executing anything) and formatting (so I can paste into WYSIWYG editors). All of this is done by simple xclip -out | ... | xclip -in.

There was a bug in stardict: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=806960

- if you selected something (i.e., copied to clipboard), it tried to look it up in a dictionary and display a translation (by default, just after startup)

- online dictionaries, including one available only over HTTP, were enabled by default

- so if you used a password manager that copies passwords into clipboard, they were immediately sent in an unencrypted request for the whole world to see

We desperately need an application firewall (something like OpenSnitch, but that's so difficult to configure correctly) and basic app isolation (like QubesOS, but that's heavy and pain to use) for Linux. It's a shame that most other OSes, despite having other problems, implement this correctly.
