The best way to contact me is to send me an email: blog at arusekk.pl. I reply after a week at most.
If it does not work, try arek_koz at o2.pl.
You can find me also on Matrix (@Arusekk:matrix.org) and Discord (@Arusekk#6609).
I sometimes lag more on those, but if you are lucky and catch me online, we can talk with the least ping.
