Don’t get me wrong, I’m happy you posted this. If there are unvoiced concerns or issues, here is a good place to discuss them.
I’m not as active on lemmy as I’d like, so I’m likely not aware of issues unless they’re raised somewhere like this.
For potential meta issues such as age verification, I’ll be seeking input from the community when they arise and information around them is known and understood.
If you’re posting as an uninvolved third party about an event you’re interested in, it’s not an ad.
As for spam, if you post a ridiculous volume about such events it could be construed as spamming. So long as you’re manually posting this shouldn’t an issue.
Basically, don’t be trying to sell anything or abusing the AZ site.
