the widespread phenomenon of internet abuse 怎樣換個說法讓意思不變？

如果只想更換widespread的話，可以用表示“到處都有”、“無處不在”的詞，比如：

the uniquitous/universal phenomenon of internet abuse

如果想換個結構，可以改為後置定語或從句或者同位語，比如：

the internet abuse, which is found here and there

the internet abuse, complaint about by the whole world

the internet abuse, a phenomenon found universally
