This problem mostly applies to people with very little SP, where breaking these guidelines can get your account temporarily limited, so it may be worth your time to read.
So here is a list of things that can keep your bandwidth usage small:
❖ #1 - avoid editing a post multiple times
my testing shows this uses about the same bandwidth as if you made another post of the same size as the one you're editing. Do yourself a favor and proof read before posting, and if you must edit later try to do it all at once. Editing out one typo at a time 10 times in a row is probably the best way to destroy your remaining bandwidth.
❖ #2 - avoid editing a comment multiple times
this is basically the same as #1, since steem treats comments roughly the same as normal posts they also have the same behavior with bandwidth usage during edits, so again you should try to edit comments as few times as possible.
❖ #3 - try not to vote too much in a single day
I break this rule all the time, but if you have very little SP and have been dishing out $0.00 votes 100 times a day chances are you're inching closer to that bandwidth limit without even knowing it, so try cutting that number in half until your votes are worth a little bit more, it might even help your curation rewards to be more critical of what you vote on.
❖ #4 - don't follow more people than you can keep up with
If you're brand new and start by following a thousand people the odds of you being able to interact with any of them after are very small because you used all your bandwidth on the follows. If you can't justify voting a hundred times per day, you should also wait to follow a thousand people or more. Once you have more SP you can support more people, be patient until then.
❖ #5 - don't claim rewards every time you have 0.001SP pending
I know it's tempting to hit claim every time you see that box, but each claim also takes some bandwidth to do, so if more are coming just distract yourself for a while and claim rewards once or twice a day at most to cut down on the number of transactions.
❖ #6 - don't resteem everything you see, your followers don't like that anyway
My testing shows a resteem uses a large amount of bandwidth, and as a general rule you shouldn't resteem more things than what someone might post in a day. 4 resteems in a day is plenty to expect your followers to read, don't go into the double digits resteeming 20 posts a day trying to get a curation bonus or you might find yourself hitting the bandwidth limit.
❖ #7 - don't add giant signatures to your posts or comments
Some people like to add some huge premade signature area with links and pictures and their life story along with everything else they can think of for you to do to help them. My version of this is very small, because this signature thing also has the problem of raising the size of each post you make. Double trouble if you have a giant signature and go to edit the post a few times later.
❖ #8 - only comment when you actually have something to say
How many times have you seen spammy comments on people's blog where they clearly didn't read the post but comment anyway? I understand this is basically TLDR.com , but there's a difference between glossing over something and talking about the topic in general, and simply having nothing to say. This is realistically the best example of something the bandwidth limit exists to prevent, so don't go around to every post you see saying something generic in hopes of getting an upvote, people don't support that anyway, you're much better off commenting on topics where you actually have something to say!
❖ #9 - POWER UP
Once you hit the bandwidth limit, you can't do this and have to wait for recharge, so stay ahead of the curve and power up each time you're able. If you win some contest or have a pile of SBD laying around, take at least half and put it into SP, there's already a lot of reasons to do it and avoiding bandwidth limitation is just an icing on the cake.
Hope this helps you guys, if there was something you didn't already know in the list or you think it will help your followers consider using some of that bandwidth you got to RESTEEM ^_-
