Please define paraliturgy
It is a term often used to describe an “unofficial” gathering of the faithful for worship usually involving some form of group prayer and/or Scripture reading, music, symbolic actions, etc, led by clergy or laypersons, which is not part of the official public worship (“Liturgy”) of the Church. These are sometimes called prayers services instead.
As such there are no rubrics to run afoul of. I suppose if something contrary to Catholic belief or something irreverent or commonly seen as inappropriate were involved, that could be labelled “abuse” but it wouldn’t technically be “liturgical abuse.”
Edited to add: Tried real hard but couldn’t resist saying maybe we could invent the term “para-liturgical abuse”

although I’m not suggesting it would apply to anything described in the OP.
