We just want to make it clear that you don’t need to give us your email to use our plugin. So, it’s unlikely and doesn’t make sense that our plugin caused your email to be hacked.
After looking at your recent comment, it seems like you might be trying to make our service look bad. It’s also possible that you didn’t actually use our plugin (the fact that both accounts “beet97” and “Mark lu” were created the same day, is also suspicious).
One thing we really care about is being open and clear. That’s why we share the source code for everything we put on our GitHub page and WP SVN. This way, anyone can look at it and understand how our services work.
