Thank you cryptkeeper,
I really appreciate the feedback! :)
I will need to make the improvements however but I will be sticking to the instant upvote service, rather than a delayed upvote. It just might take up to 30 seconds to receive the upvote instead of 3 seconds.
This is for good reason though. Using a streaming service rather than checking transactions without an upvote is not good. It means that any sort of outage anywhere and the transaction will be missed.

I'm a very big fan of keeping the instant upvote service, but I'm more dedicated to having a stable, consistent, secure service that you can trust will always be working.

Thanks again for your support!
Kind Regards, UpvoteWhale.
