RuntimeError: Event loop is closed

When running on Windows with Python 3.8, the following exception is thrown after the results of socialscan are printed.

Exception ignored in: <function _ProactorBasePipeTransport.__del__ at 0x03F71DA8>
Traceback (most recent call last):

RuntimeError: Event loop is closed

As far as I can tell, this is due to the change whereby Python 3.8 now uses ProactorEventLoop as the default event loop on Windows which causes this exception to be thrown in aiohttp. A fix appears to be scheduled for the next release of aiohttp (aio-libs/aiohttp#4324).

To avoid this error from clogging up the output, I've now set the event loop policy explicitly to SelectorEventLoop when this tool is run on Windows on Python 3.8. However, I understand that ProactorEventLoop is still the more performant event loop on Windows so I'll likely switch back to ProactorEventLoop if the upcoming release of aiohttp fixes this error.
