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)

This Plugin remains compatible with the latest version of WordPress, but I am no longer keeping up with any MBP Plugins.
MaxBlogPress plugins require a two-step registration/activation process, as well as a forced opt-in to an email-list subscription, in order to use them. This plugin circumvents those requirements, enabling unrestricted use of the plugins.
Note: this plugin does not install any other plugins. If you wish to use any MaxBlogPress plugins supported by cbnet MBP Auto-Activate, you must install them separately.
Note 2: This Plugin is not an endorsement for MaxBlogPress Plugins, but rather a proof-of-concept to demonstrate why it is futile to force users to jump through Plugin-registration and email-list-subscription hoops just to use Plugin functionality. It appears that some or all of MaxBlogPress Plugins are now released under a non-GPL-compatible license that restricts code modification. Use them at your own risk.
This plugin currently supports the following MaxBlogPress plugins:
<ul>
<li>Different Posts Per Page</li>
<li>DealDotCom Widget</li>
<li>Unblockable Popup</li>
<li>Ping Optimizer</li>
<li>Stripe Ad</li>
<li>Psychic Search</li>
<li>Favicon</li>
<li>SEO Post Link</li>
<li>Banner Ads</li>
<li>Duplicate Post Checker</li>
<li>Multi Author Comment Notification</li>
<li>Optin Form Adder</li>
</ul>
This plugin now also supports the following MaxBlogPress Revived plugins:
<ul>
<li>Front Page By Category</li>
<li>AdSense Deluxe Revived</li>
<li>Flash Fader Revived</li>
<li>Links Manage Widget</li>
<li>Banner Ads</li>
<li>Ajax Post Listing</li>
<li>Random Image</li>
<li>Access By Category</li>
<li>Captcha For Comment</li>
<li>Affiliate Image Tracker</li>
<li>Image Organizer</li>
<li>Easy Custom Fields</li>
<li>Post Ordering</li>
<li>Post Image</li>
<li>Post List By Category</li>
<li>Exerpt Listing</li>
</ul>
