I think it is better to see the profile before sending a like
What is your opinions?

I agree Lung.

It's the minimum respect

Easier to block youngsters that way.

Having the respect to read the profile is so basic, essential if anyone is genuine about seeking or cultivating any mutual relationship. Click likes... 90% voyeurism, fickle, nothing more.

Just seeing 1 picture of someone makes likes a crap shoot with the expected results.

Many Men on here dont read profiles.

I delete Dozens of viewers often.

Many are repeat viewers, Not in my age limits.

It's not a gender limited trait unfortunately. It's a by-product of spontanaity with short attention span cultivated by the social media world and era we are in. Beyond the newspaper classified where it actually once took effort and a longer time interval between reading a classified and responding, bad behaviour can magnify and becomes a worse problem today. I hate to say 'toxic masculinity', but unfortunately when you get a 'nudge' or a 'like', or sometimes receive an instant message from a member online with an empty profile (except for 'selfie' photo which is meant or supposed to increase your chance of success and a 'match' here) a few male egos can certainly be wounded and a nasty reply follow- once the guy who 'liked' your profile actually takes that respectful time to actually read the profile. Sad.
