Maciej St. Zięba was kind enough to inform me that several of his comments had never been published on this blog. I checked and they had indeed been blocked (for no reason I can understand, since they included no further links or the like) by my spam filter.
The spam filter, however, also deletes all spam messages after a few days, so that I have no idea about how often this could have happened to other readers.
Should this have happened to you as well, please let me know, so that I can “save” them and include your address among the safe ones.
Thanks for your help!
Dear Eslisa,
thank you for having quickly solved the problem – at least with my comments, I hope. With the others (if any) it might however be tricky to contact you if they are not at the same time registered with you in other scholar media, like I have informed you through Academia.edu. Otherwise informing you here would mean – posting a comment, which could be blocked again. Let’s hope no-one else is in such a strange situation.
All the best,
Maciej
I see your point, but my email address is easy to find in my webpages (here: https://stb.univie.ac.at/ueber-uns/mitarbeiter/ or here: https://www.oeaw.ac.at/ikga/team/). Thanks again!
