Doesn’t work at all and traffic usage is a concern

Not sure why this plugin is allowed on the official WP Plugin directory. The only thing that its ‘synchronisation’ does is add a whole lot of records to the postmeta table, but not a single object was ever added to the specified bucket. No errors, and no activity whatsoever on the bucket, just an email from the plugin to notify of its completion.

Traffic usage went up significantly in correlation to the synchronisation period, so it also feels dodgy, because where was all that traffic going? Unfortunately, I tried it out on a managed hosting account, which means I’m unable to investigate the nature of that traffic much further. I don’t have time to investigate the plugin code itself either right now, but felt I should at least take a couple minutes to warn others.

I don’t normally complain about free things, but no paid option is available and this is a potentially harmful plugin.
