Well... Uh... I'm not quite certain what to really say.
First off, I--- Really don't quite understand what you are actually trying to bring up or what the actual problem is really about in terms of these likes on somebodies profile.
At least, that's how I felt when I first read this thread, because I don't really understand how somebodies likes on a profile page or thread or etc is really a big problem?
So, just before making this post, I actually went to "recent activity" (which I had never actually known of prior to this thread) to actually try to get a possible understanding of what you are actually talking about, because it seems you are referencing/pointing toward heavily on the recent activity tab.
Now... I think I know what you are coming from after reading--- Sort of?
I guess you are referring to when people like a bunch of things like this?:
(Apologies if the person I am showing in the screenshot feels embarrassed or whatnot in any way, if that is a problem)
But really--- Well...
What is the problem here still?
If there is a problem here, I am totally ignorant of it myself because----
I really don't see a problem at all.
Likes are Likes; A symbol used on this forum, and other websites out there, merely--- To show one's appreciation or enjoyment or thanks for a piece of content that they, as a person enjoyed.
Why do you want to limit likes? If you feel its spammy, then tough it out, because taking or limiting that feels like we're limiting the way to express yourself or free speech or--- SOMETHING like that.
I'm heavily assuming your referring to something along the lines of that screenshot but...
If not, please call me out on it (since I am uncertain due to the wording on the post/never using recent activity.
But if indeed true then...
Really, just tough it out I say.
