Based on crashutah, apeatling https://wordpress.org/plugins/bp-disable-activation/ Disables the activation email and automatically activates new users in BuddyPress under a standard WP install and WPMU (multisite). Also, automatically logs in the new user since the account is already active.
Basically i updated the plugin and added some features like:
-Option to turn off automatic login 
-Redirect options after account creation
Known Bugs: 
-Doesn’t do the automatic login if you allow blog creation during the user creation in WPMU (multisite)

A <a href="https://codex.wordpress.org/Create_A_Network" rel="nofollow ugc">Multisite</a> Network plugin.
Ever signup a user account, delete it, and try to signup up the same username again?
Ever try to support a new user who created a username, but entered the wrong email address and so can’t activate, and can’t signup with the same username?
Ever wanted to signup a bunch of users with phony emails so users without email could start blogging right away?
I have, so I made a plugin to help me.
WP Network Multisite “mu-plugin” for user activation key removal or approval.
See Network–>Users–>”User Activation Keys” to delete activation keys – to allow immediate (re)signup of users who otherwise get the “try again in two days” message.
Also, users waiting to be activated (or can’t because the email with the generated activation link is “gone”) can be approved manually.

User Activation Keys

This plugin saved me time to delete activation key directly in the database. It's much more easier to manage users in Multisite using this plugin. Thanks for the dev!



Must Have Plugin for Multisite

Works fine :)
