It is worth connecting some kind of feedback form, as all the bots of the world send spam there. At first, we tried to sort out spam so as not to miss useful notifications. But there is so much spam that you end up catching yourself deleting everything with one click.
Therefore, please, if you need to contact us, you can always leave a comment on the publication that interests you. Spam does not get into the comments. We look forward to your comments and assessments about the work we have done. Thanks!
