I'm often facing a situation where "should + to be" form takes place. But from Grammar modal verb "should" takes a verb without particle "to". Here examples of cases:

"should + to be":

The notification should to be sent by registered mail. source

Internal dialogue to that and broader ends should to be fostered. source

"should + be":

Both were unacceptable and should be rejected.

Itinerants should be treated like all other Dutch citizens. source (pdf)

The question is what is the difference between 2 cases?

    The first two sentences are ungrammatical. Can you tell us their source?

    There are a lot of examples. You can find those having typed "should to be" in the search box of Google search engine on the news tab May 10, 2018 at 10:11
  • Well, that's surprising! I have never encountered the passive construction "should to be + past participle" before . But there are indeed examples in Google that appear to have been written by native speakers. I'm interested to know what's going on here.

  • I'd put money on people using a thesaurus incorrectly; "ought to" and "need to" are perfectly valid, but "should to" is never correct. May 10, 2018 at 11:15
  • "Ought to be" or "sure to be" are fairly common, but on the few occasions I've read "should to be" I've taken it to be a typo, or some odd dialect.

"Should to" is never correct.

Modal verbs are followed by the infinitive of another verb without to. The exceptions are ought to and used to. (Source: Oxford Learners Dictionary)
