Learn English – Alternatives to “actually”

You are mistaken in supposing this to be a recent innovation: to the best of my recollection it arose in the late 1950s. At that time it was supposed to be characteristic of the ‘beat’ community, but it entered youthspeak almost immediately and has been current among the young ever since, at least in the United States (I cannot speak to other dialects). As teenagers grow older and are called upon to address more diverse audiences more formally, they generally learn alternative expressions (as it were, so to speak, I think, in my opinion) culled from severer registers; but like never entirely disappears from speech with close friends.

It has a useful and indeed essential function in speech as a discourse marker. When it first arose it was employed primarily as an anticipatory emphatic, to signal that what follows will be of particular importance—Maynard G. Krebs’ favorite expression was “Like, wow!”—but by the end of the 60s it had acquired additional anticipatory uses: notably 1) as a signal that a subsequent pause will not mark the end of an utterance but further processing and 2) as a lexical ‘quotation mark’.

There is thus nothing to deprecate in the usage except snobbish preference for more prestigious markers. If the usage annoys you, I suggest you seek a more pretentious class of interlocutors.

Although a search on the Internet shows some dictionaries defining compromisation as "the act of compromising", it is not commonly used, and might even be grammatically incorrect (I too can't find an authoritative conclusion on this).

However, it is better replaced by an appropriate use of the word compromise.

QUESTIONABLE: Method Y lead to a compromisation of system Z.

PREFERABLE: Method Y led to a compromise of system Z.

PREFERABLE: Method Y led to system Z being compromised.

In this context, compromise is used to mean breaching a system.

There is another use of compromise which means to arrive at a mutually agreeable settlement.

QUESTIONABLE: The two parties in the accident did a compromisation.

PREFERABLE: The two parties in the accident arrived at a compromise.

PREFERABLE: The two parties in the accident compromised by agreeing to pay for their own repairs.
