Fair example, though the scale is somewhat different
Yes. Imdb has a lot of money and a lot of advertisement that would scale with usage of comment features. But even they decided to drop comments, a feature so popular, that it was rescued by moviechat.org.
Meanwhile Itch gets negative money from your comments. Is this an annoying situation that you are unable to comment? Of course. But that does not make it a sob story. The rational would be to deactivate comments for all games. Just as many developers actually did! Itch chose the lesser evil of using a hyper aggressive spam detection system.
Your oldest visible comment is 43 days old and on a game. Has that comment been approved by the developer without you noticing or how does that fit together with your claim that you could not post comments for 10 months?
And I do not understand what you mean with voided tickets and tickets still being up. Typically you do not get any answer to such a ticket. You get an automatic confirmation with the ticket number. If you do not get that confirmation, something is wrong with your mail. If you have selected any mail from Itch as being spam on a provider level, that can have unexpected consequences. There are developers that had massive problems because of such things.
Yet it has a "Community" tab at the top, curious, isn't it
Oh? I never knew. Let me adjust my browser's zoom level, so I can actually see that link (sadly, that was not a joke). You are talking about the last entry in the top bar, are you not. Let's have a look at where community leads. Hmm. It seems it leads to here, the place you are currently quite active posting and talking to other users.
I stand by my opinion. Comments on games are not the core function of Itch. Evident by how developers can deactivate it on a whim. And they can delete comments on a whim. Or approve pending comments. But most devs are too lazy for that or simply do not notice that there are pending posts.
The reason for the situation is, that it costs a lot of money and brings zero money. Staff is ddosed by all the spam comments that you do not see, since they were cought. False positives are unfortunate, but imho, better this than having hacked accounts because Itch did not enough. Read here again.
The recommended course of action is to send one (1) mail to support, explaining that you are waiting for moderation of your comments for a very long time. Do not expect an answer (but if you do not get confirmation, there is something very wrong on a deeper level). If you still cannot comment after five weeks or so, open a thread in questions & support in accordance to the rules of questions & support. Read all the rules there.
And no, those five weeks are not overly long. Developers often wait longer for more important things. Comments are lowest priority.
Oh, and if any admin reads here, please, update the rules and faqs in regard to time frames. 1-3 days is not true for a long time now. Also, consider renaming the section to questions and community support.
