I think there's a difference between a day or two and a week. The line is clearly in there somewhere. I don't think giving teams a day or two to react is a terrible thing. For example, just last week, Morse and Cespedes were due to come off the DL on Friday. Morse's game gets rained out, so he comes off the DL on Saturday, the same day Dirks went on the DL. If I had to be proactive so that my team was never illegal, I would have dropped a player Friday only to find out I didn't need to b/c I had an extra spot Saturday. Another example, Sandoval is coming off the DL today, when all the news I read said he was due back after this weekend. The point is, when you're reacting to the movements of a ML team, you need a day or two b/c you never know for sure when the moves will happen. So have a cushion at first (this is a friendly league). But if you forget and your team is illegal for a week, you lose that week (all points taken away). If you don't fix it for a couple weeks, maybe the commissioner removes the player that created the issue (guy still on the DL weeks later, guy added when no one was dropped, etc). I don't know, but the penalties for long term illegal rosters should be stiff.
