Are There Any Free Dating Sites That Are Similar To Plenty Of Fish?

I’m a widowed single Father so I don’t have a lot of time for the usual dating scene. Some female coworkers suggested I try the online dating scene and I’ve been using plenty of fish (plentyoffish.com) to try to meet someone. I like it because it is free, not like match.com or lavalife.com. But I haven’t had much success with it, there seems to be a lot of fake accounts and spam on it and I don’t have time for that run around. Are there any other sites that are similar to plenty of fish?
Thank you!
