All servers in this IRC-Network are configured to log nothing of your communication.
The only logging taking place is the storage of all Oper-Login attempts and OperServ usage attempts.
This network runs IRC services.
Registered nicknames expire after about 370 days of not being used, deleting any data associated with the nickname (memos, registered channels, settings, ...).
Unfortunately, this is a long period of time to wait for your account to expire if you lost your password.
So, in order to reset your password OR to get notified of new memos (read: offline messages) by MemoServ, you have to supply NickServ with an email address on registration.
If you absolutely do not want to give an email address, feel free to use an invalid one. However, remember that if you forget your password you will be unable to identify to NickServ and will have to wait until it expires to re-register it, as no OPER can guess that you are really who you say you are and we will not reset your password.
Only viper and someone have access to the database. No others will be granted access to the data.
This unfortunately does not protect the used software from containing exploitable bugs or the server from being hacked, so best use a password that won't matter if it gets stolen.
