I’m not sure if our unnamed wordsmith meant “blandalism” here as in
blan • dal • ism (n.)
1. willfully boring destruction or defacement of public or private property. 2. tasteless vandalism. 3. critically panned street art. 4. acts or practices of blandals. [prob. f. BLAND + VANDALISM (but with loss of “van–“)] –blan • dal • ize, v.t., –blan • dal • is • tic, adj.
Which do you think it is?
