I've never used the ignore feature but about a year ago I discovered that I had @lsutiga on ignore. He must have done something to trigger the autoignore filters.
I was ok with it being TCU, as a guy who has spent a lot of time in Funky Town and consider Tarrant County my 2nd home I'd rather it be TCU than anyone else.
There should be a "ignore tiga" default when people register. I probably have the award for being on ignore most, over the years.
