Have a question - anybody know what happened to "mom bots" which appeared for short time and then disappeared ? Was that some kind of testing these ? Will they return on 26th May or on 1st June ? Anybody know anything ?
They were only available leading up to and through Mother's Day. They were only meant to be released temporarily, like some other holiday bots

Hmm, then it is not very nice to assume that's Mother's Day date. Same thing apply to Children's Day 
.
That's why asked about 26 May and 1st June.
EDIT: So, I suppose Children's Day in 2022 will be 12 June on chess.com 
?
So far only Halloween, Christmas, and Mother's Day have had special bots.
if their is fathers day ther should be dad with jokes
Yes there is (these are dates in Poland):
26 May - Mother's Day
1 June - Children's Day
23 June - Father's Day (same date has only Nicaragua)
and globally Father's Day dates are equally scattered as Mother's and Children Day's.
In Poland there is also Grandmother's Day (21 Jan) and GrandFather's Day (22 Jan), however although it exist elsewhere, practically almost in every country its different date.
