What's the Time Limit for Posts to Stay In My Profile Subscriptions?

I find that posts are not removed after ~three months, but simply are no longer indexed or accessible by the forums' internal search. If I do a site-delimited web search as Urquhart1224 recommends for my username, I can see my posts going back almost 20 years.

I am not sure what happens if you have your username changed. That could make the web search useless.

Have checked My Subscriptions ( Me )

They go back in time to a Maximum of 3 Months

Anything Older than that, they tend to get either, Archived by Apple or outright removed by Apple

There are even limits for Apple as to how much and for how long posting can remain a active

To locate older threads that you have participated in, consider using an external search engine, with the keywords:

site:discussions.apple.com "your username"

Use quotes if your forum username has space characters in it; else that is optional.

Also consider making browser bookmarks for pages that you may want to review later again.

It's been an ongoing issue for at least the past couple of years.

For unknown reasons, long-time members typically don't have this problem. New, or newer users do.

The hosts are aware of it, but have yet to come up with a fix.

I even have the same problem. lol.

It seems to be about 3 months for me.

You’re welcome. :)
