Pete-4x4 did you translate the message from Russian to English--I cvopied and pasted one before it was removed--interesting
I recognized that it was Cyrillic. Where I am now is multi-national and I have a lot of friends who are not English based so I used Bing translator to see if it was softball related or not.
We have international tournies here with many different languages so I thought there might have been a chance it was either related to our sport - or trouble - so I took a look to see if I could help one way or the other.
Something like this happened on the SSUSA Message Board shortly after the terrorist attacks on 09/11/2001. Our best guess then, and today, is that when public events of the magnitude of the Boston Marathon bombings and related manhunt occur, internet spammers will search/target websites with the acronym "USA" as a potential recipient of their "message." Senior Softball USA possibly met their criteria. The messages were removed and the webmaster has been instructed to remove the poster's account. Hopefully, that's the end of it. Thanks, Pete.
