Old Steemers watch out! Steemit is changing rules about tags in older posts!

Hi! I have discovered something interesting.

But first of all - I'm author of MEGA statistics and analysis for TOP 50 most popular SteemIt introductions [introduceyourself] - and right now I'm doing next part of this project - TOP 100. So I have opened my list to check those who I already have. And here is surprise.

Some time ago there were no restrictions regarding amount of tags. People could put as many as they like, that's why some older posts have more than 5 of them. A week ago this kind of post was shown in all of those tags with no problem. But right now there is a change.

If you had more than 5 tags, post is visible only in first 5 of them. Of course all tags are in post but that's all.

I'm talking about that, because there are some of introductions which didn't have "introduceyourself" in first five tags so now I can't see them in proper place (like "popular"). This is why some of people won't get into Top 100 introductions next time. There are at least 4 of them:

• Hive account@b0y2k with The first ever Steemit & Crypto currency race team! ("introduceyourself" on 7th place)
• Hive account@metrox with Do you need to wear a bikini to swim with the whales? ("introduceyourself" on 8th place)
• Hive account@thebear with Steemit's First Professional Hockey Player! ("introduceyourself" on 15th place)
• Hive account@msutyler with I've Decided To Transition My Blog to SteemIt - Let the Journey Begin - The White Cliffs of Dover - Part 1 of 2 ("introduceyourself" on 15th place)

What do you think about it? Is it a good move to change the past?

And the other thing - how can I find those people?
