How strict are the current queue dodging penalties? (For someone who hasn't played for awhile)

I haven't played since October and just started playing again. I just dodged my 1st game since playing again and got a penalty, which wouldn't happen before, so I'm curious about how strict the current rules are. If there are other things you think I should be aware of please let me know. (I really don't want to read all the preseason patch notes so halp)
