Clan Rush

Bit of a mystery- wondering if anyone had any ideas. Up until 2 days ago we were a small clan of about 12. About once a month somebody would stumble upon us, sometimes stay.

Then 2 days ago people started joining And it hasn't stopped. Probably about 30 new people have joined. Not all have stayed. We are at about 29/50 now.

Does anyone know why this might be suddenly happening. What changed to cause this sudden influx. Obviously we could just set our clan to invite only but I'm sure all these people arnt just finding us randomly. Oh and I've checked that no one posted on the recruiting board ( or chat as far as I know. )
