Text me. Wanted me to "catch up" using yahoo messenger her name on there was "sammychikie44"

Some people are saying they are calling them by the fake name they use on Facebook so probably they are using an app you or one of your friends authorized on there.  They possibly want to hack your Yahoo account by getting you to click on a link.  Report the Yahoo ID to Yahoo abuse and the phone number to abuse@textplus.com
