Nah, no idea why he'd be unpopular
"In 2002, Mayweather was charged with two counts of domestic violence and one count of misdemeanor battery. He received a six-month suspended sentence and two days of house arrest and was ordered to perform 48 hours of community service.
In 2004, Mayweather was given a one-year suspended jail sentence, ordered to undergo counseling for "impulse control" and pay a $1,000 fine (or perform 100 hours of community service) after being convicted of two counts of misdemeanor battery against two women.
In 2005, Mayweather pleaded no contest to a misdemeanor battery charge after hitting and kicking a bouncer, receiving a 90-day suspended jail sentence.
On September 9, 2010, it was reported that Mayweather was being sought by police for questioning after his former girlfriend, Josie Harris, filed a domestic battery report against him. Harris accused Mayweather of battery in the past, but those charges were dropped in July 2005 after Harris testified that she had lied and that Mayweather had not battered her. Mayweather was taken into custody September 10, 2010, but was released after posting $3,000 bail. Mayweather was initially charged with felony theft (stemming from the disappearance of Harris's mobile phone); on September 16 two felony coercion charges, one felony robbery charge, one misdemeanor domestic-battery charge and three misdemeanor harassment charges were added.
On December 21, 2011, a judge sentenced Mayweather to serve 90 days in the county jail for battery upon Harris in September 2010. Mayweather reached a deal with prosecutors in which he pleaded guilty to misdemeanor battery in exchange for prosecutors dropping the felony battery charge. Mayweather also pleaded no contest to two counts of misdemeanor harassment, stemming from threats to his children. In addition to the 90-day sentence Mayweather was ordered to complete 100 hours of community service, a 12-month domestic-violence program and to pay a fine of $2,500. On June 1 Mayweather began serving his county jail sentence, and was released in August 2012."
