Chafetz Chaim issues a warning against praising someone excessively in public or before that person's enemies. Excerpt from here:
One should not praise someone in public, says the Chofetz Chaim. This is because the law of averages dictates that there will be at least one person who either is jealous of the person or has something against him—in which case the praise is sure to set off a negative reaction. The only situation where public praise is allowed is when the subject is renowned as a learned, righteous person. In such a case it is reasonable to assume that even if he has critics, they will be reluctant to speak out publicly against him, because by doing so they would lose their own credibility.
Yet in Be’er Mayim Chaim the Chofetz Chaim says that we should avoid sitting among people who are discussing a renowned Torah personality, because there are some people who simply cannot resist offering criticism no matter who the subject is. As we discussed, negative talk about such an individual is a most serious sin, as is listening to and accepting it.
In view of this rule, I have seen these activities performed in various settings, numerous times. Are these permissible or prohibited and explain why?
- Someone introduces a keynote speaker at an event and the "MC" announces his "resume" of accomplishments such as "He has received the Pulitzer Prize for 5 books"
- The rabbi praises the Bar or Bat Mitzvah's accomplishments by announcing to the shul the awards and high grades the person earned
- At a Yeshiva University dinner I attended years ago, between the various speakers, they scrolled the names of the donors with "tiered amounts". Suffice to say that the highest tier was about 1 million dollars. It makes those that donate $10,000 seem like "nebbishes".
- Giving awards (plaques, gifts, medals, etc.) to designated honorees at yeshiva dinners or fund-raisers, etc.
- Praising the chatan or kalah at a sheva brachot bys stating how beautiful s/he is; how they overcame tough challenges in life; how charming, generous. wealthy the families are
- Praising the dead person at a funeral
No doubt, there are many other similar situations. Please address as many of the above as you can. Perhaps, there is a general rule that applies to all of the above that indicates when or how you can or can't praise someone in light of Chafetz Chaim's ruling?
