Some have the custom to cover up the unplastered square (Zecher Lachurban) during Adar. Yes, it sounds crazy, but I figure, better have a Zecher Lachurban for 11/12 (or 12/13) months, than zero…
Likewise, some have the custom to give Machtzis Hashekel for the unborn. Yes, it’s a Chumrah. But perhaps this will slow down the Heterim for abortion.
And so on.
