Anyone Having Trouble Recruiting?

I’m an officer in my guild and have been responsible recruiting for raids. I haven’t been responsible for this in a guild before. Our ambitions aren’t too lofty, just want to maintain a core 10 man team to do the content with. This has been a lot tougher than expected as I keep running into the issue that people join the guild, are sociable, sign up for the raid, etc, and then don’t show on their first raid night and either leave the guild the next day or vanish and have stopped logging in. It’s pretty disheartening and has happened multiple times now. Is this just a common thing to be expected?
