Paper author has not included all suggestions in peer review
The author owns the paper. They should consider any suggestions you make but need not implement any specific recommendation. Give up your &quot;personal&quot; feelings. That isn't your job. Re evaluate the paper on its merits and give it a fair assessment.
You are, of course, allowed to repeat your old suggestions, but it is a mistake to judge it solely on whether all of your suggestions were followed.
Some, but not all, authors will state in a &quot;rebuttal&quot; their reasons for ignoring suggestions. It isn't normally required. Judge the paper as it appears before you. Complain to the editor if you must.
Also consider that some really good suggestions are saved for future work by authors rather than included in the present paper. The work may already be in progress.
