7 rules to follow online, according to an etiquette expert

Facebook, Venmo, and Tinder launched less than a decade ago, but since their inception, unspoken rules about proper “netiquette” have changed radically.

Tech Insider consulted online etiquette expert Daniel Post-Seining for some tips. He’s the great-great-grandson of Emily Post, the longtime publisher of etiquette guides and author of “Manners in a Digital World.”

From heated political debates on Facebook to messaging Tinder matches, here’s how Post-Senning says we can all get along better online.

How long to wait before texting your crush back:

When replying to someone you want to date via text message, respond within one to three hours. Otherwise, you may seem uninterested.

'A text conversation can go stale in a few hours,' Post-Senning says. 'Don't just make them wait.'

If you're crushing on someone, don't play mind games, he adds. Healthy relationships aren't created by gaining emotional power over people by withholding texts.

When it's ok to break up through text:

While text break-ups don't usually seem polite, Post-Senning says there are some circumstances when it's ok.

You can only go the text message route it if you're in the beginning stages of the relationship, he says. Etiquette is about honouring a relationship based on a mutual set of emotional expectations. If the majority of your interactions have happened over text and you've gone on less than five dates with them, a text will suffice.

In that circumstance, if a person you're not interested in asks for a follow-up date, try something like: 'I'm glad we've had the chance to go out, but I'm not interested. Thanks for asking.'

When ghosting is acceptable:

Ghosting -- aka ending a (usually casual) relationship by ignoring their texts and remaining silent -- always feels disrespectful.

But Post-Senning says there's one instance in which it might be ok: when you both decide to ghost at the same time.

'Sometimes if it's a mutual ghosting, it can be nice to let the relationship fade away,' he says.

How to get matches on Tinder:

Crafting an attractive Tinder profile is an art form.

If your Tinder game hasn't been so hot recently, Post-Senning says to follow these tips: post photos that actually look like you, reply within a few hours, and message your match something clever and specific to what they wrote on their profile.

When to request money on Venmo:

When a troll says something mean, your first instinct may be to say something mean back.

But the biggest tool in your arsenal is not responding, Post-Senning says. The ability to ignoring trolls is both underrated and very powerful.

How to debate politics on Facebook:

Presidential election season in the US is officially in full swing, which means plenty of Facebook posts (and arguments) about Trump and Clinton are inevitable.

Post-Senning advises the following for engaging in (and surviving) them:

1) First, decide if it's worth it.

2) Avoid political discussion on holidays.

3) Show respect, and don't question someone's intelligence or integrity.

4) Illustrate your point with a specific, living example.

5) Listen.

6) Know when to retreat from commenting and your Newsfeed.
