Due amount of spam "members" / inactive accounts etc etc. I have delated all accounts what has not been active for year or more. This will happen once in a while in future. Inactive and apparently spam related accounts will get deleted. If you log in once in a while - be it every 6 months or so - it will be enough to keep account safely here.
If you have been among the deleted and one day want to sign in, please register again. Same if your account was for reason or another accidentally deleted, which should not happen.
Being registered user is not necessity unless you want to post (or use search). All content is possible to read without logging in / registering.
