answering my own emails because of it, and yes it has happened.
there are even alot of things that can happen in a year but I am fairly confident that if a guest didn't short me, beat me, or try something unsafe with me that a year later they still will be of the same mindset. However over a year and I start to feel less confident so I decline to give reference over the year.
The other is when I get so many reference requests from a single gent that litterally they outweight my own emails/requessts. For example and this is many years ago I would get 4-5emails within a day with all of the ladies requesting reference on the same guy. the 1st got the he's good, 2nd got he's good but I just gave a reference on him 2mins ago and so on. A few days later i would get another influx of 4-5 email requests, again same guy. This happened about a month after a visit and continued a few weeks and more the 20 requests later that I called him private and let him know that while I was glad he was confident in me to provide a reference the excessive nature was becoming a problem and he would need to use a new reference as I did not have time to deal with his requests anymore. He understood and just said he got excited especially since the ladies who had previously declined now would meet because I now knew him.
So, for me that is what I am ready to give my guests. If they would like another reference after a year, they need to come back and refresh my memory BCD or use a new reference.
I wish more guests would email to let us know who they will be using us as a reference for, I spend alot of time looking up these ladies to make sure they are safe to share a reference with. It would cut that time out since I would know in advance they wished me to give this lady an ok, and that she is not a crazy wife/GF trying to garner info or LE trying to entrap me with saying I have seen people and trying to get details. There is so much more to an ok then just saying he is ok.
Overuse, I just say no and ask them to use one of the newer ladies they had to have seen in the last 20 requests I answered. Just because I might be more well known or trusted doesn't mean you should abuse the privilege, we do it to help you and the other provider without exception of anything in return....
