Looks like embeds don't work when it's in a community, since that's the only difference I can see between the ones that work and the ones that don't.
Why did you jump to assuming auto-vote harvesting without even considering technical issues being a possibility?
There must be a reason it didn't work, hopefully you get to the bottom of it.
No apology for accusing me of auto-vote harvesting?
Looks like farming to me my friend. So, no apology required. Two posts in the same hour, almost no comment interaction from you outbound or from others inbound on your posts, and yet you can post multiple times a day? Almost all of the (very few) comments on your posts you don't even bother to answer.
You're quick to comment when you get a downvote though.
You're well rewarded, you should probably be content with that. Also, please remember that none of the rewards in your posts are yours until they pay out and they can be removed.
You can act as you see fit though, fail to interact, post as many times as you like, just like others can act as they see fit. That's what freedom means.
Someday I'll stop being surprised when people who seem cool at first turn out not to be.
You are free to have your opinion of course, that's what freedom is all about. I applaud you applying your right to act and think as you see fit; others will also, don't be surprised. Freedom is something we should all enjoy.
