Has Pros and Cons

If you use it in fairly standard ways, it’s fine. However, I have two major issues with it. The first is that when recently updating the plugin, it did not reactivate after updating. In the short window of time when the plugin was inactive, an executive from our largest client was looking at the site and found that anyone could access it without logging in. We may lose this client because of that. The other issue is that all the plugin data is stored in a serialized array in the user meta table. This is a bad practice. Because it is stored in a serialized array it makes it difficult/inefficient to do custom programming using information from the plugin. In order to access the data you have to first unserialize it, or you can query using regex, which is not always going to return reliable results.
