It is better not to be bothered.
I often
help with attributions, sometimes adding extensive historical or numismatic notes. I do this for the benefit of a wider audience who may be interested. Often I spend an hour digging out information, finding photos, building a story, then I write the message and then I move on. Perhaps the original poster drops a thank-you, perhaps not, but to be honest I don't keep track because my pleasure has been got from providing an answer to the wider world. I really am not aware whether my replies are acknowledged, so I can't possibly be hurt.
But exactly the opposite happens sometimes. I also pose questions or engage in debates. Sometimes I have multiple helpful replies and to be honest I'm not sure whether I always individually respond on each of them. I sometimes think of
writing a generic "thank you to all who replied" note but that seems insincere and impersonal. If something strikes me as worth special comment I write back to the author, but sometimes there's an answer where I think "yes that confirms what I've been thinking, and it tallies with what others are saying" and for one or other reason distraction sets in, I move on, and I don't think of responding personally. As I get many multiple messages on numismatic topics each day, there is a greater-than-zero chance of
writing to me and not always getting a personal response. Believe me, it's not personal. I've trouble enough with my scattered memory keeping track of many people who've written me with a question or comment which simply demands a reply from me, to be also able to reply to many more people who have written with information intended to be helpful.
In response to the original poster, if "it" does bother you, then I would encourage you spend the anxious energy in further numismatic research and in
writing even more helpful online responses. Forgive, please continue to debate, but don't be hurt if you don't always get individual replies. There are practical reasons and they
work both ways.
