I don't ECM...just 7-zip ultra compression, obscure archive name (usually split too) with a simple password (same for all my uploads). I don't use the site name as my password.
Think I've only had one upload removed from my mega account in the years I've used it, but then I don't mass upload stuff. I think they reduced the account data size since I started using them (I'm not sure if my account is still 50GB or it got reduced).
