I created this tool and have been using it in my instance since the very beginning. My instance is almost 2 years old and it’s total database size is 60.2GB.

What people don’t understand about this tool is:

• If a community is generating enough activity, it’s likely that someone from your instance is already following that community.
• If a community isn’t generating enough activity, it won’t create much of a network/storage burden anyway.

Sure, it will make a small difference, but it’s nothing compared to the benefits it provides.
