In most cases, once you have put the (new) safeguards in place then a prosecution is unlikely to be the appropriate response. To that extent, therefore, it is to make it less likely that these cases will be prosecuted.
In summary, there is a clear distinction between four types of case: the first three to be robustly prosecuted, the fourth (offensive messages) to be treated very differently.
The fourth one is probably there where the more difficult decisions have been in recent months and certainly where there's been a growth in decisions. There we've put in a double safeguard: high threshold and unlikely to be in the public interest.
It doesn't mean no cases but it certainly puts in that double safeguard before a case is brought.
